[PATCH v2 2/4] slub: Actually use 'message' in restore_bytes()

From: Stephen Boyd
Date: Tue May 25 2021 - 22:56:38 EST


The message argument isn't used here. Let's pass the string to the
printk message so that the developer can figure out what's happening,
instead of guessing that a redzone is being restored, etc.
