BKL: Remove BKL from ext3_put_super() and ext3_remount()
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. Signed-off-by: Jan Blunck <jblunck@infradead.org> Acked-by: Jan Kara <jack@suse.cz> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
