Subject: mm/damon/sysfs-schemes: support DAMOS_FILTER_TYPE_AGE_MS
Date: Thu, 05 Nov 2026 18:05:56 -0800

Support use of DAMOS_FILTER_TYPE_AGE_MS via DAMON sysfs ABI.  Add a user
keyword "age_ms" for configuring a filter of the type using the existing
filter configuration interface.  Reuse existing 'min' and 'max' sysfs
files in the filter configuration directory for storing the age range in
milliseconds.
