Linus,
please pull the latest slab changes from
git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-5.19
======================================
- Conversion of slub_debug stack traces to stackdepot, allowing
more useful debugfs-based inspection for e.g. memory leak
debugging. Allocation and free debugfs info now includes full
traces and is sorted by the unique trace frequency.
The stackdepot conversion was already attempted last year but
reverted by ae14c63a9f20. The memory overhead (while not actually
enabled on boot) has been meanwhile solved by making the large
stackdepot allocation dynamic. The xfstest issues haven't been
reproduced on current kernel locally nor in -next, so the slab
cache layout changes that originally made that bug manifest were
probably not the root cause.
- Refactoring of dma-kmalloc caches creation.
- Trivial cleanups such as removal of unused parameters, fixes
and clarifications of comments.
- Hyeonggon Yoo joins as a reviewer.
Thanks,
Vlastimil
