From d6b636ebb1c9f412687a7b6ed97c996247cc2380 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 9 May 2018 10:03:56 -0700 Subject: xfs: halt auto-reclamation activities while rebuilding rmap Rebuilding the reverse-mapping tree requires us to quiesce all inodes in the filesystem, so we must stop background reclamation of post-EOF and CoW prealloc blocks.
