The mm selftests are timing out with the current 180-second limit.
Testing shows that run_vmtests.sh takes approximately 11 minutes
(664 seconds) to complete.
Increase the timeout to 900 seconds (15 minutes) to provide sufficient
buffer for the tests to complete successfully.

Gee, that's a bit crude, isn't it. I have a laptop which will need 90000 ;)
I guess it's better than it was before. Some sort of smarter monitor
of ongoing activity can be bothered about later.

900s is crude, and I can imagine some systems needing even more time!
I think the real issue is run_vmtests.sh bundles many tests together. Most finish quickly but few (e.g. compaction) tests take significant time.
I agree that a smarter approach with per-test timeouts would be better.
Thanks,
Shivank
