* mm: cleancache: s/flush/invalidate/Dan Magenheimer2012-01-237-44/+51
| | | | | | | | | | | | | | | | | | | | | | | | Per akpm suggestions alter the use of the term flush to be invalidate. The next patch will do this across all MM. This change is completely cosmetic.

| | | | | | | | | | | | | | | | | | | | | | If there are any inodes on the super block that have been unlinked (i_nlink == 0) but have not yet been deleted then prevent the remounting the super block read-only.

| * vfs: count unlinked inodesMiklos Szeredi2012-01-072-54/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new counter to the superblock that keeps track of unlinked but not yet deleted inodes. Do not WARN_ON if set_nlink is called with zero count, just do a ratelimited printk. This happens on xfs and probably other filesystems after an unclean shutdown when the filesystem reads inodes which already have zero i_nlink. Reported by Christoph Hellwig.

| * vfs: protect remounting superblock read-onlyMiklos Szeredi2012-01-074-5/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently remouting superblock read-only is racy in a major way. With the per mount read-only infrastructure it is now possible to prevent most races, which this patch attempts. Before starting the remount read-only, iterate through all mounts belonging to the superblock and if none of them have any pending writes, set sb->s_readonly_remount. This indicates that remount is in progress and no further write requests are allowed. If the remount succeeds set MS_RDONLY and reset s_readonly_remount. If the remounting is unsuccessful just reset s_readonly_remount. This can result in transient EROFS errors, despite the fact the remount failed. Unfortunately hodling off writes is difficult as remount itself may touch the filesystem (e.g. through load_nls()) which would deadlock. A later patch deals with delayed writes due to nlink going to zero.

Export kill_bdev as well, so brd doesn't have to open code it. Reduce buffer_head.h requirement accordingly. Removed a rather large comment from invalidate_bdev, as it looked a bit obsolete to bother moving. The small comment replacing it says enough.
