Merge #15650: Handle the result of posix_fallocate system call
5d35ae3326 Handle the result of posix_fallocate system call (Luca Venturini)
Pull request description:
The system call `posix_fallocate` is not supported on some filesystems.
- catches the result of posix_allocate and fall back to the default behaviour if the return value is different from 0 (success)
Fixes #15624
