Hi,

I am running 6.12.0 for a week, and today I notice several strange
items in /proc/allocinfo:

       -4096 18446744073709551615 mm/filemap.c:3787 func:do_read_cache_folio
 -1946730496 18446744073709076340 mm/filemap.c:1952 func:__filemap_get_folio
  -903294976 18446744073709331085 mm/readahead.c:263 func:page_cache_ra_unbounded
  -353054720 18446744073709465421 mm/shmem.c:1769 func:shmem_alloc_folio
 10547565210        0 mm/compaction.c:1880 func:compaction_alloc
  -156487680 18446744073709513411 mm/memory.c:1064 func:folio_prealloc
 -2422685696 18446744073708960140 mm/memory.c:1062 func:folio_prealloc
 -2332479488 18446744073708982163 fs/btrfs/extent_io.c:635 [btrfs] func:btrfs_alloc_page_array

some values are way too large, seems like corrupted/uninitialized, and values for compaction_alloc 
are inconsistent: non-zero size with zero count.

I do not know when those data became this strange, and I have not reboot my system yet.
Do you guys need extra information before I reboot my system and started to try reproducing?


Thanks
David
