1906 | 1) PosixCreateX - to set and return the mode, inode#, device info and | |
1907 | perhaps add a CreateDevice - to create Pipes and other special .inodes | |
1908 | Also note POSIX open flags | |
1909 | 2) Close - to return the last write time to do cache across close more safely | |
1910 | 3) PosixQFSInfo - to return statfs info | |
1911 | 4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes) | |
1912 | 5) Mkdir - set mode | |
1913 | ||
1914 | And under consideration: | |
1915 | 6) FindClose2 (return nanosecond timestamp ??) | |
1916 | 7) Use nanosecond timestamps throughout all time fields if | |
1917 | corresponding attribute flag is set | |
1918 | 8) sendfile - handle based copy | |
1919 | 9) Direct i/o | |
1920 | 10) "POSIX ACL" support | |
