The patch titled
Subject: fs/affs: free affs_sb_info in put_super()
has been removed from the -mm tree. Its filename was
fs-affs-free-affs_sb_info-in-put_super.patch
This patch was dropped because it was nacked
------------------------------------------------------
From: Fabian Frederick <fabf@xxxxxxxxx>
Subject: fs/affs: free affs_sb_info in put_super()
kill_block_super() calls generic_shutdown_super() calling FS
->put_super() where we generally free superblock specific information.
This removes unneeded affs_kill_sb()
sbi is automatically reserved in fill_super() so there is no
need to test it.
