From 0c4c516fa206d6e8a3986eebd3016a96022792c6 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Wed, 22 Jun 2022 14:45:11 -0400 Subject: fs: dlm: remove additional dereference of lksb This patch removes a dereference of lksb of lkb when calling ast tracepoint. First it reduces additional overhead, even if traces are not active. Second we can deference it in TP_fast_assign from the existing lkb parameter.
