XFSTests generic/436: lseek misbehaves(?) in the presence of holes. #21

Closed stevenjswanson closed 7 years ago

Probably related to #22.

The problem may be with the test. xfstests/src/seek_sanity_test.c does a simple check to see whether SEEK_HOLE and SEEK_DATA should actually report the locations of holes and data (it sets the default_behavior flag, if it does not.

If they should report actual hole location, the test is particular about where the holes should be. It seems that NOVA's behavior is allowed by the lseek manpage's description of SEEK_DATA and SEEK_HOLE.

Fixed by adjusting xfstests. NVSL/xfstest@bb28a88b5772f97e073476131c2cfb6e8f676a96
