https://git.shady.money/linux/atom?h=master2025-11-03T16:16:02ZDocumentation/driver-api/cxl: remove page-allocator quirk section2025-11-03T16:16:02ZGregory Pricegourry@gourry.net2025-10-03T14:32:32Zurn:sha1:82b5d7e30b24b7df5dbf10aea97292be38daf88d
The node/zone quirk section of the cxl documentation is incorrect.
The actual reason for fallback allocation misbehavior in the
described configuration is due to a kswapd/reclaim thrashing scenario
fixed by the linked patch. Remove this section.
