2154 1) PosixCreateX - to set and return the mode, inode#, device info and
2155 perhaps add a CreateDevice - to create Pipes and other special .inodes
2156 Also note POSIX open flags
2157 2) Close - to return the last write time to do cache across close more safely
1982c344
SF		 2158 3) FindFirst return unique inode number - what about resume key, two
2159 forms short (matches readdir) and full (enough info to cache inodes)
2160 4) Mkdir - set mode
1da177e4
LT		 2161

1982c344

2184 WRITE_AND_X
2185 LOCKING_AND_X (note posix lock semantics)
2186 RENAME (note rename across dirs and open file rename posix behaviors)
2187 NT_RENAME (for hardlinks) Is this good enough for all features?
2188 FIND_CLOSE2
2189 TRANSACTION2 (18 cases)
2190 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2191 (BB verify that never need to set allocation size)
2192 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
