Linus Torvalds 52e44129fb Merge branch 'for-5.12-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu ... Pull percpu fix from Dennis Zhou: "This contains a fix for sporadically failing atomic percpu allocations. I only caught it recently while I was reviewing a new series [1] and simultaneously saw reports by btrfs in xfstests [2] and [3]. In v5.9, memcg accounting was extended to percpu done by adding a second type of chunk. I missed an interaction with the free page float count used to ensure we can support atomic allocations. If one type of chunk has no free pages, but the other has enough to satisfy the free page float requirement, we will not repopulate the free pages for the former type of chunk. This led to the sporadically failing atomic allocations" Link: https://lore.kernel.org/linux-mm/20210324190626.564297-1-guro@fb.com/ [1] Link: https://lore.kernel.org/linux-mm/20210401185158.3275.409509F4@e16-tech.com/ [2] Link: https://lore.kernel.org/linux-mm/CAL3q7H5RNBjCi708GH7jnczAOe0BLnacT9C+OBgA-Dx9jhB6SQ@mail.gmail.com/ [3] * 'for-5.12-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu: percpu: make pcpu_nr_empty_pop_pages per chunk type		2021-04-10 12:51:12 -07:00
