+Subject: [PATCH] Fix wrong exclusion of slab pages on Linux 6.2-rc1
+
+* Required for kernel 6.2
+
+Kernel commit 130d4df57390 ("mm/sl[au]b: rearrange struct slab fields to
+allow larger rcu_head"), which is contained in Linux 6.2-rc1 and later,
+made the offset of slab.slabs equal to page.mapping's one.  As a result,
+"makedumpfile -d 8", which should exclude user data, excludes some slab
+pages wrongly because isAnon() returns true when slab.slabs is an odd
+number.  With such dumpfiles, crash can fail to start session with an
+error like this:
+
+  # crash vmlinux dumpfile
+  ...
+  crash: page excluded: kernel virtual address: ffff8fa047ac2fe8 type: "xa_node shift"
+
+Make isAnon() check that the page is not slab to fix this.
