The upstream commit cb code had a few bugs: 1) The arguments of the list_move_tail() call in txg_dispatch_callbacks() were reversed by mistake. This caused the commit callbacks to not be called at all. 2) ztest had a bug in ztest_dmu_commit_callbacks() where "error" was not initialized correctly. This seems to have caused the test to always take the simulated error code path, which made ztest unable to detect whether commit cbs were being called for transactions that successfuly complete. 3) ztest had another bug in ztest_dmu_commit_callbacks() where the commit cb threshold was not being compared correctly. 4) The commit cb taskq was using 'max_ncpus * 2' as the maxalloc argument of taskq_create(), which could have caused unnecessary delays in the txg sync thread.

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
Documentation for building, configuring, and using ZFS can be found at: http://wiki.github.com/behlendorf/zfs/
