From: Darrick J. Wong <djwong@xxxxxxxxxx> This test runs 500 iterations of a "fill the fs and try to punch" test. Hole punching can be particularly slow if, say, the filesystem is mounted with -odiscard and the DISCARD operation takes a very long time. In extreme cases, I can see test runtimes of 4+ hours. Constrain the runtime of _test_full_fs_punch by establishing a deadline of (30 seconds * TIME_FACTOR) and breaking out of the for loop if the test goes beyond the time budget. This keeps the runtime within the customary 30 seconds. Signed-off-by: "Darrick J.
