From 160b5a784525e8a44902873f1938e1f4d77fe112 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 16 Apr 2019 08:22:00 -0700 Subject: [PATCH] xfs: hoist the already_fixed variable to the scrub context Now that we no longer memset the scrub context, we can move the already_fixed variable into the scrub context's state flags instead of passing around pointers to separate stack variables.
