22 | - work around linux kernel bug (at least in 3.2): kernel might |
|
|
23 | trash fiemap input arguments. |

|
|
27 | truncates segment count if a file. |
|
|
28 | - make fh argument of IO::AIO::mmap optional, also add mmap/munmap |
|

|
|
40 | - provide SEEK_HOLE and SEEK_DATA, if available. |
|
