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!

1873 For better POSIX semantics from Linux client, (even better

1875
1876 1) PosixCreateX - to set and return the mode, inode#, device info and
1877 perhaps add a CreateDevice - to create Pipes and other special .inodes
1878 Also note POSIX open flags
1879 2) Close - to return the last write time to do cache across close more safely
1880 3) PosixQFSInfo - to return statfs info
1881 4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
1882 5) Mkdir - set mode
1883
1884 And under consideration:
1885 6) FindClose2 (return nanosecond timestamp ??)
1886 7) Use nanosecond timestamps throughout all time fields if
1887 corresponding attribute flag is set
1888 8) sendfile - handle based copy
1889 9) Direct i/o
1890 10) "POSIX ACL" support
1891 11) Misc fcntls?
1892
1893 what about fixing 64 bit alignment

1901 TREE_CONNECT_ANDX (BB which wct?)

1903 LOGOFF_ANDX
1904 DELETE (note delete open file behavior)
1905 DELETE_DIRECTORY
1906 READ_AND_X
1907 WRITE_AND_X
1908 LOCKING_AND_X (note posix lock semantics)
1909 RENAME (note rename across dirs and open file rename posix behaviors)
1910 NT_RENAME (for hardlinks) Is this good enough for all features?
1911 FIND_CLOSE2
1912 TRANSACTION2 (18 cases)
1913 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
1914 (BB verify that never need to set allocation size)
1915 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
1916
1917 COPY (note support for copy across directories) - FUTURE, OPTIONAL

1919 setting Linux xattrs perfectly) - OPTIONAL
1920 dnotify - FUTURE, OPTIONAL
1921 quota - FUTURE, OPTIONAL
