GNU testsuite comparison:

Skipping an intermittent issue tests/tail/inotify-dir-recreate (passes in this run but fails in the 'main' branch)
Note: The gnu test tests/tail/tail-n0f is now being skipped but was previously passing.
Congrats! The gnu test tests/rm/many-dir-entries-vs-OOM is now passing!

Footnotes

1. 46 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (62594c0) during the generation of this report, so c79e686 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

The current changes look good to me, though I don't know if you plan to add further changes due to the PR being a draft.
