Subject: [PATCH] [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.
