From 6df9f9a253c7dc9f8ed18bf89d762de350a31813 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Fri, 17 Jun 2016 07:31:27 -0500 Subject: gfs2: Lock holder cleanup Make the code more readable by cleaning up the different ways of initializing lock holders and checking for initialized lock holders: mark lock holders as uninitialized by setting the holder's glock to NULL (gfs2_holder_mark_uninitialized) instead of zeroing out the entire object or using a separate flag. Recognize initialized holders by their non-NULL glock (gfs2_holder_initialized). Don't zero out holder objects which are immeditiately initialized via gfs2_holder_init or gfs2_glock_nq_init.
