From f253a9796b492c6b2095ed18ea6a9540a8f30d9b Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 16 Nov 2017 22:11:32 -0600 Subject: [PATCH] xfs: scrub the secondary superblocks Source kernel commit: 21fb4cb1981ef7e02f35a42b2a5ae619517dfe1b Ensure that the geometry presented in the backup superblocks matches the primary superblock so that repair can recover the filesystem if that primary gets corrupted.
