* : 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.
