[PATCH 07/27] BKL: Remove BKL from ext3_put_super() and ext3_remount()

[Jan Blunck <jblunck@suse.de>]

The BKL lock is protecting the remounting against a potential call to
ext3_put_super(). This could not happen, since this is protected by the
s_umount rw semaphore of struct super_block.

Therefore I think the BKL is protecting nothing here.
