From 435dcf0787fde20d99ede873cf56dc27c22f2c30 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Fri, 1 Feb 2019 09:08:49 -0800 Subject: xfs: never try to scrub more than 64 inodes per inobt record Make sure we never check more than XFS_INODES_PER_CHUNK inodes for any given inobt record since there can be more than one inobt record mapped to an inode cluster.
