Subject: [PATCH v2 0/2] mm/damon: Fix fake /proc/loadavg reports
Date: Thu, 25 Nov 2021 16:08:28 +0000	[thread overview]
Message-ID: <> (raw)

This patchset fixes DAMON's fake load report issue.  The first patch
makes yet another variant of usleep_range() for this fix, and the second
patch fixes the issue of DAMON by making it using the newly introduced

I think these need to be applied on v5.15.y, but the second patch cannot
cleanly applied there as is.  I will back-port this on v5.15.y and post
later once this is merged in the mainline.  If you think this is not
appropriate for stable tree, please let me know.


From v1
- Avoid copy-and-pasting usleep_delay() in DAMON code (Andrew Morton)

SeongJae Park (2):
  timers: Implement usleep_idle_range()
  mm/damon/core: Fix fake load reports due to uninterruptible sleeps
