[GIT PULL] slab for 5.19

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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  cache layout changes that originally made that bug manifest were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
