Changelog since V2 o Fix list corruption issue (hughd) o Tighen up locking protocol (hughd) o Micro-optimisations (hughd)
Changelog since V1 o Use trylock in free_unref_page_list due to IO completion from softirq context (yuzhao)
This was a standalone patch but now split in two. The main changes since v2 are fixing the issues exposed by Hugh's shmfs stress test.
Patch 1 is a long-standing issue that is technically a bug but happened to work because of how it was used.
Patch 2 leaves IRQs enabled for most PCP allocations with more details in the changelog itself.
-- 2.35.3
