[PATCH v2 0/3] slab: fix and cleanup of slub_debug

Posted by Chengming Zhou 1 year, 8 months ago

Changes in v2:
- Change check_object() to do all the checks without skipping, report
  their specific error findings in check_bytes_and_report() but not
  print_trailer(). Once all checks were done, if any found an error,
  print the trailer once from check_object(), suggested by Vlastimil.
- Consolidate the two cases with flags & SLAB_RED_ZONE and make the
  complex conditional expressions a little prettier and add comments
  about extending right redzone, per Vlastimil.
- Add Reviewed-by from Feng Tang.
- Link to v1: https://lore.kernel.org/r/20240528-b4-slab-debug-v1-0-8694ef4802df@linux.dev
