git/t/t5317-pack-objects-filter-objects.sh
Ævar Arnfjörð Bjarmason b2e5d75d17 tests: mark tests as passing with SANITIZE=leak 
When the "ab/various-leak-fixes" topic was merged in [1] only t6021
would fail if the tests were run in the
"GIT_TEST_PASSING_SANITIZE_LEAK=check" mode, i.e. to check whether we
marked all leak-free tests with "TEST_PASSES_SANITIZE_LEAK=true".

Since then we've had various tests starting to pass under
SANITIZE=leak. Let's mark those as passing, this is when they started
to pass, narrowed down with "git bisect":

- t5317-pack-objects-filter-objects.sh: In
  faebba436e (list-objects-filter: plug pattern_list leak, 2022-12-01).

- t3210-pack-refs.sh, t5613-info-alternate.sh,
  t7403-submodule-sync.sh: In 189e97bc4b (diff: remove parseopts member
  from struct diff_options, 2022-12-01).

- t1408-packed-refs.sh: In ab91f6b7c4 (Merge branch
  'rs/diff-parseopts', 2022-12-19).

- t0023-crlf-am.sh, t4152-am-subjects.sh, t4254-am-corrupt.sh,
  t4256-am-format-flowed.sh, t4257-am-interactive.sh,
  t5403-post-checkout-hook.sh: In a658e881c1 (am: don't pass strvec to
  apply_parse_options(), 2022-12-13)

- t1301-shared-repo.sh, t1302-repo-version.sh: In b07a819c05 (reflog:
  clear leftovers in reflog_expiry_cleanup(), 2022-12-13).

- t1304-default-acl.sh, t1410-reflog.sh,
  t5330-no-lazy-fetch-with-commit-graph.sh, t5502-quickfetch.sh,
  t5604-clone-reference.sh, t6014-rev-list-all.sh,
  t7701-repack-unpack-unreachable.sh: In b0c61be320 (Merge branch
  'rs/reflog-expiry-cleanup', 2022-12-26)

- t3800-mktag.sh, t5302-pack-index.sh, t5306-pack-nobase.sh,
  t5573-pull-verify-signatures.sh, t7612-merge-verify-signatures.sh: In
  69bbbe484b (hash-object: use fsck for object checks, 2023-01-18).

- t1451-fsck-buffer.sh: In 8e4309038f (fsck: do not assume
  NUL-termination of buffers, 2023-01-19).

- t6501-freshen-objects.sh: In abf2bb895b (Merge branch
  'jk/hash-object-fsck', 2023-01-30)

1. 9ea1378d04 (Merge branch 'ab/various-leak-fixes', 2022-12-14)
