|
* : Tag zfs-0.4.8 - Use 'git log --no-merges' for full change log.
|
||||||
|
|
||||||
|
* : Build system improvements:
|
||||||
|
- Remove Module.markers and Module.symver{s} in clean target.
|
||||||
|
- Improved kernel source detection when none specified.
|
||||||
|
- Fix RPM definitions for the unknown distro/installation.
|
||||||
|
- Check for spl in ../spl if not found in install path.
|
||||||
|
- Include all headers regardless of depth in packages.
|
||||||
|
- Allow recursive configure/make.
|
||||||
|
|
||||||
|
* lib/libzpool/kernel.c: Fixed several zdb bugs when opening a pool
|
||||||
|
- zdb wasn't getting the correct device size when the vdev is a
|
||||||
|
block device. In Solaris, fstat64() returns the device size but
|
||||||
|
in Linux an ioctl() is needed.
|
||||||
|
- make sure that we don't try to open a block device in write mode
|
||||||
|
from userspace. This shouldn't happen, because zdb opens devices
|
||||||
|
in read-only mode, and ztest only uses files.
|
||||||
|
|
||||||
|
* lib/libspl/include/umem.h: Add umem_alloc_aligned() and honor
|
||||||
|
cache_align field for umem cache. Under linux we open block devices
|
||||||
|
with O_DIRECT which means we must provide aligned memory buffers.
|
||||||
|
|
||||||
|
* lib/libzpool/kernel.c: Fix some incorrect error handling. In
|
||||||
|
vn_open(), if fstat64() returned an error, the real errno was being
|
||||||
|
obscured by calling close().
|
||||||
|
|
||||||
|
* scripts/*: Fix scripts to work when invoked from other directories.
|
||||||
|
|
||||||
|
* module/zfs/arc.c: Fix struct ht_lock padding in arc.c.
|
||||||
|
|
||||||
|
* lib/libefi/include/sys/uuid.h: Fix duplicate uuid_t typedef.
|
||||||
|
|
||||||
|
* module/zfs/txg.c: Use CPU percentages for number of commit cb
|
||||||
|
threads. This doesn't change number of threads in the kernel, but it
|
||||||
|
reduces number of threads in ztest (important due to 32-bit address
|
||||||
|
limitations).
|
||||||
|
|
||||||
|
* cmd/ztest/ztest.c: Clean up emulation of kernel threads in
|
||||||
|
userspace. Updated to use pthread thread specific data rather than
|
||||||
|
keeping a global list. This also fixes at least one easily
|
||||||
|
reproducible crash in ztest
|
||||||
|
|
||||||
|
* META, config/kernel.m4: Add configure check for kernel build
|
||||||
|
options which are incompatible with the license. If your building
|
||||||
|
against a kernel deemed incompatible configure will fail and
|
||||||
|
suggest how you should rebuild your kernel.
|
||||||
|
|
||||||
|
* config/kernel-fmode-t.m4: Linux 2.6.28 compat, add a check for the
|
||||||
|
fmode_t type. This typedef first appears in 2.6.28 kernels as part
|
||||||
|
of some block device operation reworking.
|
||||||
|
|
||||||
|
* module/zfs/dmu_send.c: No inline to keep dmu_recv_stream() stack
|
||||||
|
frame less than 1024 bytes. Recent builds against 2.6.31 flagged
|
||||||
|
dmu_recv_stream() as stack heavy. Further analysis of this function
|
||||||
|
should be performed to further reduce its stack usage.
|
||||||
|
|
||||||
|
* scripts/common.sh: Split the udev rule from a specific configuration
|
||||||
|
by providing a generic 60-zpool.rules file which uses a small helper
|
||||||
|
util 'zpool_id' to parse a configuration file by default located in
|
||||||
|
/etc/zfs/zdev.conf. The helper script maps a by-path udev name to a
|
||||||
|
more friendly name of <channel><rank> for large configurations.
|
||||||
|
|
||||||
|
Additionally, when running zpool-create.sh in-tree it will no longer
|
||||||
|
use udev because we would have to copy certain helper scripts in to
|
||||||
|
the installed system. To avoid this the config file in simply
|
||||||
|
parsed and symlinks are created in your working tree. The script
|
||||||
|
will use udev if it as run as part of an installed zfs-test package.
|
||||||
|
|
||||||
|
* module/zfs/zvol.c: Use check_disk_change() instead of
|
||||||
|
revalidate_disk(). For 2.6.27 kernels are earlier revalidate_disk()
|
||||||
|
was not available. However, check_disk_change() has been available
|
||||||
|
for far longer and will properly inform the kernel of the volume
|
||||||
|
change for both older and newer kernels.
|
||||||
|
|
||||||
|
* module/zfs/dmu.c: Fixed incorrect ASSERT3S() added by ZVOL.
|
||||||
|
|
||||||
|
* module/zfs/vdev_raidz.c, module/zfs/zvol.c: Minor fixes for 32-bit.
|
||||||
|
|
||||||
|
* scripts/zfs-update.sh, man/man8/*: Added man pages based on the
|
||||||
|
latest documentation and modified zfs-update.sh script to update them.
|
||||||
|
|
||||||
|
* .gitignore: Updated .gitignore rules to exclude build products.
