Linus Torvalds1da177e2005-04-16 15:20:36 -07002464 1) PosixCreateX - to set and return the mode, inode#, device info and

2466 Also note POSIX open flags
Steve French50c2f752007-07-13 00:33:32 +00002467 2) Close - to return the last write time to do cache across close

Steve French50c2f752007-07-13 00:33:32 +00002469 3) FindFirst return unique inode number - what about resume key, two
Steve French1982c342005-08-17 12:38:22 -07002470 forms short (matches readdir) and full (enough info to cache inodes)
