From 32934280967d00dc2b5c4d3b63b21a9c8638326e Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Tue, 14 Aug 2018 11:09:52 -0700 Subject: [PATCH] Btrfs: clean up scrub is_dev_replace parameter struct scrub_ctx has an ->is_dev_replace member, so there's no point in passing around is_dev_replace where sctx is available.
