Synopsis: 9.0_RC1 pagedaemon spins

State-Changed-From-To: open->closed
State-Changed-By: tsutsui%NetBSD.org@localhost
State-Changed-When: Thu, 12 Aug 2021 01:29:20 +0000
State-Changed-Why:
The spin seems caused by drmkms leaks and that have been fixed 
in recent src/sys/external/bsd/drm2/linux/linux_reservation.c
rev 1.12, 1.13, and 1.14 as noted in PR/55089.

uvm_pdaemon.patch provided by mlelstv@ could still be useful on
memory starvation, but I would like to discuss it in another PR.

I guess the audio problem on NetBSD 8.1 mentioned in this PR
might be a different issue.
