2022-09-04	common: disable infinite IO error retry for EIO shutdown tests	Darrick J. Wong
	This patch fixes a rather hard to hit livelock in the tests that test how xfs handles shutdown behavior when the device suddenly dies and starts returing EIO all the time. The livelock happens if the AIL is stuck retrying failed metadata updates forever, the log itself is not being written, and there is no more log grant space, which prevents the frontend from shutting down the log due to EIO errors during transactions. While most users probably want the default retry-forever behavior because EIO can be transient, the circumstances are different here. The tests are designed to flip the device back to working status only after the unmount succeeds, so we know there's no point in the filesystem retrying writes until after the unmount. This fixes some of the periodic hangs in generic/019 and generic/475. Signed-off-by: Darrick J.
