14 | extents. |
| 16 | 4.0 |
15 | - work around linux kernel bug (at least in 3.2): kernel might |
|
|
16 | trash fiemap input arguments. |

18 | set FIEMAP_EXTENT_LAST on last segment. |
|
|
19 | - make fh argument of IO::AIO::mmap optional, also add mmap/munmap |
|
|
20 | to quick overview. |
|
|
21 | - splice can corrupt data. |
|
|
22 | - (libeio) remove pread/pwrite emulation. |
|

29 | - experimental support for IO::AIO::splice and ::tee (no aio_...). |
|
|
30 | - provide SEEK_HOLE and SEEK_DATA, if available. |
|
|
31 | - work around (again!) an immensely stupid bug in RHEL, defining |
|
|
32 | autoconf macros in linux system headers (analysed by Paul Howarth). |

|
|
51 | - (libeio) added syncfs syscall wrapper. |
|
|
52 | - (libeio) set thread name on linux (ps -L/Hcx, top, gdb). |

|
55 | - tune treescan #threads and #outstanding requests a bit. |
|
|
56 | - reduce the number of file descriptors in use at any one time |

59 | in aio_scandir and treescan. |
|
|
60 | - reduce compiled size by ~10% by not inlining some key functionality. |
