* omfs: add file routinesBob Copeland2008-07-26
| | | | | | | | | Add functions for reading and manipulating the storage of file data in the extent-based OMFS. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* omfs: add directory routinesBob Copeland2008-07-26
| | | | | | | | | | | Add lookup and directory management routines for OMFS. The filesystem uses hashing based on the filename and stores collisions, unordered, in siblings of files' inode structures. To support telldir, the current position in the hash table is encoded in fpos.
