generic: ENOSPC regression test in a multi-threaded scenario
Test allocation strategies of the file system and validate space
anomalies as reported by the system versus the allocated by the
program.
The test is motivated by a bug in ext4 systems where-in ENOSPC is
reported by the file system even though enough space for allocations is
available[1].
