+
+ * : 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.
