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:
