It's an opened file, for crying out loud! If there is anything that makes sure that superblock will stay alive, that is it... And lose the "locked" argument, please. The sane solution is to make get_active_super() return it unlocked and have your freeze_bdev() simply grab s_umount. Unconditionally. I'll do the first part in #untested in a minute or so (and make it grab s_umount in the current variant of code in fs/block_dev.c); then your patch would shift taking s_umount down into freeze_super(). -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
