* : Tag zfs-0.4.5 - Use 'git log --no-merges' for full change log.
* FC11 and SLES11 support: This includes all compatibility changes
to support 2.6.29 based kernels and the required build system
improvements.
* lib/libspl/asm-generic/atomic.c: Generic user space atomic support.
* module/zpios/zpios.c: Register a basic compat ioctl handler for
32-bit user vs 64-bit kernel compatibility. This is the default
build environment for all 64-bit SLES systems. Additionally
replace the use of 'struct timespec' which uses longs internally
and is therefore different sizes on 32-bit vs 64-bit objects with
'struct zpios_timespec_t'.a
* config/kernel.m4: Check arch/default path when detecting kernel
objects under SLES. We still preferentially use arch/arch if
available but if that fails it is acceptable to use default.
* config/kernel.m4: Remove LINUXINCLUDE from autoconf wrapper.
This breaks the 2.6.28+ kernels build system, all kernel build systems
at least post 2.6.16 will set this properly so we should not.
* lib/libspl/include/assert.h: Add ASSERTV macro to simplify removing
variables (the V in ASSERTV) which are only used in ASSERT().
Also revert all previously modified ASSERT()s to their original
definitions and use the ASSERTV macro to handle unused variables.
* module/zpios/zpios.c: Use spl device interfaces for portability.
* scripts/common.sh: The losetup -f option is unavailable for
SLES10 use the unused_loop_device() common function. Additionally
LOSETUP is now used to portably reference the losetup binary.
* module/zfs/vdev_disk.c: Unused destroy_dirty_buffers arg removed.
* module/zfs/vdev_disk.c: BIO_RW_SYNC renamed to BIO_RW_SYNCIO.
* module/zfs/vdev_disk.c: open/close_bdev_excl() renamed to
open/close_bdev_exclusive().
* module/zfs/vdev_disk.c: Empty write barriers are supported as of
linux 2.6.24 and are now used to implement DKIOCFLUSHWRITECACHE.
* module/zfs/vdev_disk.c: The bi_end_io API changes make partial
IO's impossible handle this case cleanly.
* module/zfs/vdev_disk.c: BIO_RW_FAILFAST replaced with
BIO_RW_FAILFAST_{DEV|_TRANSPORT|_DRIVER}, use the legacy
BIO_RW_FAILFAST flag if it exists for now.
* module/zfs/dmu_objset.c, module/zfs/spa_history.c: Excessively
large stack frames (>2048) were detected in dmu_objset_snapshot()
and spa_history_log() and were reduced by allocating from the heap.
* Rebased to ZFS b117 from OpenSolaris:
* module/zfs/dmu.c: Update zerocopy patch to be consistent with
new flags arg passed to dmu_read().
* module/zpios/zpios.c: Update zpios to be aware of the new flags
argument available in dmu_read(). Additionally add a zpios command
line flag to set the DMU_READ_NO_PREFETCH flag for a test.
* module/zfs/include/sys/zfs_context.h: Wrap new sysevent includes
until sysevent or something like it is implemented.
* module/zfs/zfs_ioctl.c: Wrap all the ACL interfaces with HAVE_ZPL.
They are integrated with the vfs layer which is not yet supported.
* module/zcommon/zfs_prop.c: Export new quota related symbols.
* lib/libzfs/libzfs_util.c: Increase buffer size for nvlist which
is needed for large configurations.
* lib/libzpool/kernel.c: Reimplement user kthreads based on pthread
thread specific data. This resolves previous scalabily concerns about
the cost of calling curthread which previously required a list walk.
* Bug fixes:
* lib/libspl/include/sys/zfs_debug.h: Removed duplicate file.
* lib/libspl/include/sys/isa_defs.h: Fixed missing macro definitions
for little endian and big endian.
* cmd/zpios/zpios_main.c: Pretty-up the zpios 'make check' output.
* module/zfs/vdev_disk.c: Honor spa_mode() when opening block devs.
* module/zfs/vdev_disk.c: Initial error handling added to
vdev_disk_io_done() to revalidate the media on EIO.
* lib/libzfs/libzfs_util.c: Fix an accidentally introduced formatting
issue in zfs_nicenum() output.

* : Tag zfs-0.4.4 - Use 'git log --no-merges' for full change log.
* : Generic distro friendly build system / packaging improvements
for RPM based distros including CHAOS, RHEL, Fedora, and SLES.
These changes bring the zfs-0.4.4 tree in to compliance with
the spl-0.4.4 packaging changes. The bottom line is 2 source
rpms and 4 binary rpms will now be generated when creating
packages there will be:
zfs-<version>.src.rpm
- Fully rebuildable source rpm for libzfs and utils.
zfs-modules-<version>.src.rpm
- Fully rebuildable source rpm for kernel modules.
zfs-<version>.<arch>.rpm
- Binary rpm for libzfs and utils. The utils in this package are
compatible with all zfs-module rpms of the same version.
zfs-devel-<version>.<arch>.rpm
- Binary rpm containing headers for building against libzfs libraries.
zfs-modules-<verion>-<kernel>.arch.rpm
- Binary rpm containing the kernel modules for a specific kernel build.
The package name contains the kernel version and you should have one
of these packages installed to match every kernel on your system.
zfs-modules-devel-<verion>-<kernel>.arch.rpm
- Binary rpm containing development header and module symbols needed
for building additional kernel modules which are dependent on the
zfs module stack.
* : SLES9/10 distro support added: Several significant updates to
the build system were required to support this including:
- Autoconf macros updated to be aware of the standard install
locations for SLES kernel sources and build objects. Additionally
changes were made to support multiple names for Module{s}.symvers.
- By default on SLES all user space builds are 32-bit even on
64-bit arches. This means we need to be careful to pass -m64 in
the autoconf checks which probe the kernel. Additionally,
ioctl_compat handles still need to be added so 32-bit user
binarys can perform ioctls with the 64-bit kernel.
* : Powerpc64 support added:
- 64-bit user space atomic support for power64 was obtained from
an old version of OpenSolaris which offered minimal powerpc support.
The atomic support is not 100% fully implemented but it's a good
first step towards cleanly supporting the architecture.
- Added powerpc ISA type.
- Explictly use signed char for portability. On x86/x86_64
systems the default char type is signed, on ppc/ppc64 systems
the default char type is unsigned.
- Core target arch support for conditional compilation of SUBDIRs.
Required by libspl for its arch specific atomic implementations.
* COPYRIGHT: Readded accidentally dropped COPYRIGHT, it just
references the OPENSOLARIS.LICENSE which was still in the project.
* module/zfs/dmu_tx.c: Add EXPORT_SYMBOL(dmu_tx_callback_register).
* config/user-zlib.m4: Add basic zlib autoconf check for user space.
2009-03-20 Brian Behlendorf <behlendorf1@llnl.gov>
* : Tag zfs-0.4.3 - Use 'git log --no-merges' for full change log.
* : Rebased to ZFS b108 from OpenSolaris
* configure.ac, *Makefile.am: Build system update. This includes
resolving various build issues and adding support for the remaining
common build targets. Available targets now include:
- make all # Build everything
- make install # Install everything
- make clean # Clean up build products
- make distclean # Clean up everything
- make dist # Create package tarball
- make srpm # Create package source RPM
- make rpm # Create package binary RPMs
- make tags # Create ctags and etags for everything
Extra care was taken to ensure that the source RPMs are fully
rebuildable against Fedora/RHEL/Chaos kernels. To build binary
RPMs from the source RPM for your system simply run:
rpmbuild --rebuild zfs-x.y.z-1.src.rpm
This will produce two binary RPMs with correct 'requires'
dependencies for your kernel. One will contain all zfs modules
and support utilities, the other is a devel package for compiling
additional kernel modules which are dependent on the zfs.
zfs-x.y.z-1_<kernel version>.x86_64.rpm
zfs-devel-x.y.2-1_<kernel version>.x86_64.rpm
* config/kernel.m4, config/Rules.am: Removed the build options
-Wno-unused -Wno-missing -Wno-unused -Wno-parentheses and
-Wno-unknown-pragmas. All upstream warnings which were being
suppressed by these options are now handled in the matching
gcc-* topic branch.
* zpios: Various zpios and test infrastructure improvements.
* feature-commit-cb: New feature commit callbacks.
* : Various bug fixes which are more clearly detailed in the
git commit logs. For a detailed summary of changes post version
0.4.2, check out the 'top' topic branch and view the commit logs.

2009-02-05 Brian Behlendorf <behlendorf1@llnl.gov>
* : Tag zfs-0.4.2
* lib/libzfs/libzfs_util.c: Remove mknod() this is now handled by
by the SPL with an upcall even without GPL-only symbols.
* module/zfs/vdev_diskc: Updated linux vdev_disk interfaces to issue
multiple bios if needed due to the maximum request size being smaller
than the request size passed down from the spa.
* scripts/zpool-config/lo-*: Add loopback based test configs.
2009-01-21 Brian Behlendorf <behlendorf1@llnl.gov>
* : Tag zfs-0.4.1
* : Rebased to ZFS b105 from OpenSolaris
* : Restructured project and build system to more closely
mirror the code organization used in OpenSolaris. This
allows us minimize the changes to upstream source needed,
and allows concurrent user+kernel space builds of all components.
2008-11-19 Brian Behlendorf <behlendorf1@llnl.gov>
* : Tag zfs-0.4.0
* : ZFS project migrated from Subversion which leveraged a
quilt based patch stack to Git and a TopGit managed patch
stack. The new method treats all patches as Git branches
which can be more easily shared for distributed development.
Consult the top level GIT file for detailed information on
how to properly develop for this package using Git+TopGit.
2008-11-12 Brian Behlendorf <behlendorf1@llnl.gov>
* : Tag zfs-0.3.4
* zfs-07-create-dev-zfs.patch:
Ricardo M. Correia <Ricardo.M.Correia@sun.com>
- Make libzfs create /dev/zfs if it doesn't exist.
* zfs-05-check-zvol-size.patch:
Ricardo M. Correia <Ricardo.M.Correia@sun.com>
- Properly check zvol size under Linux.
* zfs-04-no-openat-fdopendir.patch:
Ricardo M. Correia <Ricardo.M.Correia@sun.com>
- Do not use openat() and fdopendir() since they are not available
on older systems.
* zfs-03-fix-bio-sync.patch:
Ricardo M. Correia <Ricardo.M.Correia@sun.com>
- Fix memory corruption in RHEL4 due to synchronous IO becoming
asynchronous.
2008-11-06 Brian Behlendorf <behlendorf1@llnl.gov>

* zfs-01-zpios-arg-corruption.patch:
Ricardo M. Correia <Ricardo.M.Correia@sun.com>
- Fix zpios cmd line argument corruption problem.
* zfs-00-minor-fixes.patch:
Ricardo M. Correia <Ricardo.M.Correia@sun.com>
- Minor build system improvements
- Minor script improvements
- Create a full copy and not a link tree with quilt
- ZPIOS_MAJOR changed from 231 to 232
- BIO_RW_BARRIER flag removed from IO request
2008-06-30 Brian Behlendorf <behlendorf1@llnl.gov>
* : Tag zfs-0.3.3
* : Minor script updates and tweaks to be compatible with
the latest version of the SPL.
2008-06-13 Brian Behlendorf <behlendorf1@llnl.gov>
* vdev_disk.diff: Replace vdev_disk implementation which was
based on the kmalloc'ed logical address space with a version
which works with vmalloc'ed memory in the virtual address space.
This was done to support the new SPL slab implementation which
is based on virtual addresses to avoid the need for contigeously
allocated memory.
2008-06-05 Brian Behlendorf <behlendorf1@llnl.gov>
* arc-vm-integration.diff: Reduce maximum default arc memory
usage to 1/4 of total system memory. Because all the bulk data
is still allocated on the slab memory fragmentation is a serious
concern. To address this in the short term we simply need to
leave lots of free memory.
* fix-stack.diff: First step towards reducing stack usage so
we can run the full ZFS stack using a stock kernel.
2008-06-04 Brian Behlendorf <behlendorf1@llnl.gov>
* : Tag zfs-0.3.2
* : Extensive improvements to the build system to detect kernel
API changes so we can flexibly build with a wider range of kernel
versions. The code has now been testing with the 2.6.18-32chaos
and 2.6.25.3-18.fc9 kernels, however we should also be compatible
with other kernels in the range of 2.6.18-2.6.25. The only
remaining issue preventing us from running with a stock
kernel is ZFS stack usage.
2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
* : Tag zfs-0.3.1
* : License headers including URCL added for release.
2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
* : Tag zfs-0.3.0
* configure.ac: Improved autotools support and configurable debug.
2008-05-15 Brian Behlendorf <behlendorf1@llnl.gov>
* : Updating original ZFS sources to build 89 which
includes the new write throttling changes plus support
for using ZFS as your root device. Neither of which
will work exactly right without some more work but this
gets us much closers to the latest source.
2008-02-28 Brian Behlendorf <behlendorf1@llnl.gov>
* : First attempt based on SPL module and zfs-lustre sources
