From 631fc955bdc86c3fed5880cba80c663d1b32e0c2 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 9 May 2018 10:02:00 -0700 Subject: [PATCH] xfs: clean up scrub usage of KM_NOFS All scrub code runs in transaction context, which means that memory allocations are automatically run in PF_MEMALLOC_NOFS context. It's therefore unnecessary to pass in KM_NOFS to allocation routines, so clean them all out. Signed-off-by: Darrick J.
