fileio rndrw : FATAL: Failed to fsync file! file: 0 errno = 22 (Invalid argument)
On a system installed with Oracle Linux 7 the rndwr tests are failing. (rndrd and the rest work fine)

FATAL: Failed to fsync file! file: 0 errno = 22 (Invalid argument)
When I enable debug it shows:
DEBUG: Executing request, operation: 2, file_id: 86, pos: 15089664, size: 16384 DEBUG: Executing request, operation: 3, file_id: 127, pos: 0, size: 0 DEBUG: Executing request, operation: 1, file_id: 98, pos: 2785280, size: 16384 FATAL: Failed to fsync file! file: 0 errno = 22 (Invalid argument) DEBUG: Executing request, operation: 1, file_id: 92, pos: 10747904, size: 16384 DEBUG: Executing request, operation: 2, file_id: 5, pos: 3211264, size: 16384 Done.
I submitted what I think is a fix to this issue here: https://github.com/akopytov/sysbench/pull/518 . Any test/review is appreciated.
