[PATCH v2 0/3] slab: fix and cleanup of slub_debug
From: Chengming Zhou
Date: Wed Jun 05 2024 - 03:16:01 EST
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@xxxxxxxxx
