From: Kunwu Chan <[email protected]>
This series fixes several bugs in the DAMON selftests. Most are
trivial but cause tests to silently pass when they shouldn't, or
fail prematurely on slow machines.
Patch 1 fixes mutable default arguments in DamonCtx.__init__()
that cause state to leak between test instances.
Patch 2 fixes a trailing comma in DamosFilter that turns
memcg_path from a string into a tuple, silently breaking memcg
filter setup.
Patch 3-4 fix bugs in damos_tried_regions.py: wrong operator
precedence drops the "not met" prefix from failure output, and
empty early aggregation cycles cause premature test failure.
Patch 5 fixes several wrong strings that produce dead elif
branches, skipped file existence checks, and broken dict key
lookups.
Based on next-20260529.
