From 9862ca056e654633e521b303f74fb123f7f17e98 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Wed, 25 Jan 2017 12:50:47 -0500 Subject: GFS2: Switch tr_touched to flag in transaction This patch eliminates the int variable tr_touched in favor of a new flag in the transaction. This is a step toward reducing contention on the gfs2_log_lock spin_lock.
