-Subject: fix detection of typed (compound) pages (Linux 6.12)
-Git-commit: 72c3414949bd2e9284c8ba7ceaf109a5a34ac2e1
-References: bsc#1237269
-Link: https://lore.kernel.org/kexec/20241122101219.936746-1-david@redhat.com/
-Upstream: merged

-* Required for kernel 6.12
-
-Ever since kernel commit 4ffca5a96678c ("mm: support only one page_type
-per page"), page types are no longer flags (PG_slab, PG_offline, ...)
-stored in page->_mapcount, but values stored in the top byte.
-
-Because we currently try deriving flags from the mapcount values to
-check for slab and hugetlb pages, we get:
-(1) "false positives" from isSlab(), making us not detect free (buddy)
-    pages and offline pages anymore.
-(2) "false positives" when detecting hugetlb pages.
-
-In the common case we now simply dump all memory, and fail to exclude
-offline and free (buddy) pages, assuming they are all slab pages,
-which is bad.
-
-We should just consistently compare the page->_mapcount with the unmodified
-PAGE_*_MAPCOUNT_VALUE, like we already did for free (buddy) and offline
-pages already. This also works for older kernels, because the kernel never
-supported having multiple page types set on a single page, so there was
-never the need to derive flags from the PAGE_*_MAPCOUNT_VALUE.
-
-It is worth noting that the lower 24bit of the page->_mapcount field
-can be used while a page type is set. This is, however, currently not
-the case for any of the involved page types (slab, buddy, offline,
-hugetlb). In the future, the kernel could either just tell us the types,
-or provide a mask to be applied to the page->_mapcount ("bits to ignore")
-when comparing the values. But, there might be bigger changes coming up
-with the "memdesc" work in the kernel, where the type would not longer
-be stored in page->_mapcount ... so for now we can keep it simple.
