[PATCH 00/39] Union mounts - return d_ino from lower fs
After questioning the value of d_ino, I am now convinced of its utility. This version of union mounts fills in d_ino of fallthru directory entries with the inode number of the target. You still need to stat() the entry to get st_dev if you want to do a file uniqueness comparison using the inode. See the patch ... 8 Aug 2010 12:19

[PATCH 03/39] VFS: Add read-only users count to superblock
While we can check if a file system is currently read-only, we can't guarantee that it will stay read-only. The file system can be remounted read-write at any time; it's also conceivable that a file system can be mounted a second time and converted to read-write if the underlying fs allows it. This is a problem f... 8 Aug 2010 12:19

[PATCH 22/39] union-mount: Add generic_readdir_fallthru() helper
In readdir(), client file systems need to lookup the target of a fallthru in a lower layer for three reasons: (1) fill in d_ino, (2) fill in d_type, (2) make sure there is something to fall through to (and if not, don't return this dentry).
