[PATCH 0/2] mm/damon: fix memory leak in memcg_path sysfs file

[SeongJae Park]

Users can leak memory by repeatedly writing a string to DAMOS sysfs
memcg_path file.  Fix it (patch 1) and add a selftest (patch 2) to avoid
reoccurrance of the bug.

SeongJae Park (2):
  mm/damon/sysfs-schemes: free old damon_sysfs_scheme_filter->memcg_path
    on write
  selftets/damon: add a test for memcg_path leak
