When replaying an unlink/remove operation via zfs_rmdir() the object being removed will be instantiated by a call to zfs_dirent_lock(). This means that there is a single reference protecting the object. Right before the call to zfs_inode_update() this reference is dropped which may cause the object to be destroyed. This will result in a NULL dereference as shown by the stack trace is issue #782. This likely isn't an issue during normal operation because there is always an additional reference held on the object by the VFS. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #782 |

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
