Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ Also note POSIX open flags
+ 2) Close - to return the last write time to do cache across close more safely
+ 3) PosixQFSInfo - to return statfs info
+ 4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
+ 5) Mkdir - set mode
+
+ And under consideration:
+ 6) FindClose2 (return nanosecond timestamp ??)
+ 7) Use nanosecond timestamps throughout all time fields if

+ 8) sendfile - handle based copy
+ 9) Direct i/o

+ LOCKING_AND_X (note posix lock semantics)

+ NT_RENAME (for hardlinks) Is this good enough for all features?
+ FIND_CLOSE2
+ TRANSACTION2 (18 cases)
+ SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
+ (BB verify that never need to set allocation size)
+ SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)

+ COPY (note support for copy across directories) - FUTURE, OPTIONAL
