|
||||
* : 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.
