[PATCH 0/3] slub: Print non-hashed pointers in slub debugging

From: Stephen Boyd
Date: Wed May 19 2021 - 21:36:03 EST


I was doing some debugging recently and noticed that my pointers were
being hashed while slub_debug was on the kernel commandline. Let's make
the prints in here meaningful in that case by pushing %px throughout.

Alternatively, we could force on no_hash_pointers if slub_debug is on
the commandline. Maybe that would be better?

The final patch is just something else I noticed while looking at the
code. The message argument is never used so the debugging messages are
not as clear as they could be.

Stephen Boyd (3):
lib/hexdump: Add a raw pointer printing format for slub debugging
slub: Print raw pointer addresses when debugging
slub: Actually use 'message' in restore_bytes()
