When calling sa_update() and friends it is possible that a spill buffer will be needed to accomidate the update. When this happens a hold is taken on the new dbuf and that hold must be released before calling dmu_tx_commit(). Failing to release the hold will cause a copy of the dbuf to be made in dbuf_sync_leaf(). This is done to ensure further updates to the dbuf never sneak in to the syncing txg. This could be left to the sa_update() caller. But then the caller would need to be aware of this internal SA implementation detail. It is therefore preferable to handle this all internally in the SA implementation. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #503 Closes #513 |

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!
$ ./configure
$ make pkg
To copy the kernel code inside your kernel source tree for builtin compilation:
$ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
$ ./copy-builtin /usr/src/linux-...
Full documentation for building, configuring, and using ZFS can be found at: http://zfsonlinux.org
