This series fixes several bugs in the DAMON selftests. Most are trivial but makes test output wrong or even silently pass the one test case for 'avail_operation' file existence check.
Patch 1 fixes mutable default arguments in DamonCtx.__init__() that cause state to leak between test instances. Patch 2 fixes wrong operator precedence and join TypeError in damos_tried_regions.py. Patch 3 fixes several wrong strings that produce dead elif branches, skipped file existence checks, and broken dict key lookups.
