2146 perhaps add a CreateDevice - to create Pipes and other special .inodes
2147 Also note POSIX open flags

1982c344
SF		 2149 3) FindFirst return unique inode number - what about resume key, two

2151 4) Mkdir - set mode

LT		 2152

2177 RENAME (note rename across dirs and open file rename posix behaviors)
2178 NT_RENAME (for hardlinks) Is this good enough for all features?
2179 FIND_CLOSE2
2180 TRANSACTION2 (18 cases)
2181 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2182 (BB verify that never need to set allocation size)
