When zpl_fill_super -> zfs_domount fails (e.g. because the dataset was destroyed before it could be successfully mounted) the subsequent call to zpl_kill_sb -> zfs_preumount would derefence a NULL pointer. This bug can be reproduced using this shell script: #!/bin/sh ( while true; do zfs create -o mountpoint=legacz tank/bar zfs destroy tank/bar done ) & ( while true; do mount -t zfs tank/bar /mnt umount /mnt done ) & Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #639
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
