[PATCH 1/1 linux-next] fs/affs: free affs_sb_info in put_super()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



kill_block_super() calls generic_shutdown_super() calling FS
put_user() 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.
