Subject[PATCH 0/5] SLUB debugfs improvements based on stackdepot

this series combines and revives patches from Oliver's last year
bachelor thesis (where I was the advisor) that make SLUB's debugfs
files alloc_traces and free_traces more useful.
The resubmission was blocked on stackdepot changes that are now merged,
as explained in patch 2.

Patch 1 is a new preparatory cleanup.

Patch 2 originally submitted here [1], was merged to mainline but
reverted for stackdepot related issues as explained in the patch.

Patches 3-5 originally submitted as RFC here [2]. In this submission I
have omitted the new file 'all_objects' (patch 3/3 in [2]) as it might
be considered too intrusive so I will postpone it for later. The docs
patch is adjusted accordingly.

Also available in git, based on v5.17-rc1:

I'd like to ask for some review before I add this to the slab tree.


Oliver Glitta (4):
mm/slub: use stackdepot to save stack trace in objects
mm/slub: aggregate and print stack traces in debugfs files
mm/slub: sort debugfs output by frequency of stack traces
slab, documentation: add description of debugfs files for SLUB caches

Vlastimil Babka (1):
mm/slub: move struct track init out of set_track()
