However, that series was heavily criticized. I was not intending on following up on it. If reworking the mlock_count is beneficial for other reasons, I am happy to respin it if the work needed to make it mergeable is minimal. Otherwise, I don't think I have the time to revisit (but feel free to pick up the patches if you'd like). [1]https://lore.kernel.org/lkml/20230720070825.992023-1-yosryahmed@xxxxxxxxxx/
