logfs: destroy the reserved inodes while unmounting
We were assuming that the evict_inode() would never be called on reserved inodes. However, (after the commit 8e22c1a4e logfs: get rid of magical inodes) while unmounting the file system, in put_super, we call iput() on all of the reserved inodes. The following simple test used to cause a kernel panic on LogFS: 1. Mount a LogFS file system on /mnt 2. Create a file $ touch /mnt/a 3. Try to unmount the FS $ umount /mnt The simple fix would be to drop the assumption and properly destroy the reserved inodes. Signed-off-by: Prasad Joshi <prasadjoshi.linux@gmail.com>
