From 7975e465af6b46e9d0eaf94f764922dc92b28d9c Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 7 Jun 2021 09:34:50 -0700 Subject: [PATCH] xfs: drop IDONTCACHE on inodes when we mark them sick When we decide to mark an inode sick, clear the DONTCACHE flag so that the incore inode will be kept around until memory pressure forces it out of memory. This increases the chances that the sick status will be caught by someone compiling a health report later on. Signed-off-by: Darrick J.
