[PATCH 06/10] Docs/admin-guide/mm/damon/usage: fix wrong example of DAMOS filter matching sysfs file

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The example usage of DAMOS filter sysfs files, specifically the part of
'matching' file writing for memcg type filter, is wrong.  The intention
is to exclude pages of a memcg that already getting enough care from a
given scheme, but the example is setting the filter to apply the scheme
to only the pages of the memcg.  Fix it.
