2229 For better POSIX semantics from Linux client, (even better

2231
2232 1) PosixCreateX - to set and return the mode, inode#, device info and
2233 perhaps add a CreateDevice - to create Pipes and other special .inodes
2234 Also note POSIX open flags
2235 2) Close - to return the last write time to do cache across close more safely
1982c344
SF		 2236 3) FindFirst return unique inode number - what about resume key, two
2237 forms short (matches readdir) and full (enough info to cache inodes)
2238 4) Mkdir - set mode
1da177e4
LT		 2239
2240 And under consideration:
1982c344
SF		 2241 5) FindClose2 (return nanosecond timestamp ??)
2242 6) Use nanosecond timestamps throughout all time fields if
1da177e4 2243 corresponding attribute flag is set
1982c344

2245 8) Direct i/o
2246 9) Misc fcntls?

2256 TREE_CONNECT_ANDX (BB which wct?)

2263 LOCKING_AND_X (note posix lock semantics)
2264 RENAME (note rename across dirs and open file rename posix behaviors)
2265 NT_RENAME (for hardlinks) Is this good enough for all features?

2286 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2287 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2288 Actually need QUERY_FILE_UNIX_INFO since has inode num
2289 BB what about a) blksize/blkbits/blocks
2290 b) i_version
2291 c) i_rdev
2292 d) notify mask?
2293 e) generation
2294 f) size_seqcount
2295 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2296 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2297 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
