     Subject: selftests/damon/_damon_sysfs: find sysfs mount point from /proc/mounts
has been removed from the -mm tree.  Its filename was
     selftests-damon-_damon_sysfs-find-sysfs-mount-point-from-proc-mounts.patch

Subject: selftests/damon/_damon_sysfs: find sysfs mount point from /proc/mounts
Date: Fri, 3 May 2024 11:03:11 -0700

_damon_sysfs.py assumes sysfs is mounted at /sys.  In some systems, that
might not be true.  Find the mount point from /proc/mounts file content.
