From 1b8550b5de7610027609ef605f85dc29f1d9da82 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Fri, 30 Jul 2021 12:40:25 -0500 Subject: gfs2: Mark journal inodes as "don't cache" Before this patch, journal inodes were considered regular inodes, which meant that instead of evicting them, function iput_final would just put them on the lru for later processing. If the file system withdrew for whatever reason, the withdraw would never be seen until the inode was evicted, which could be indefinitely. This patch marks all journal inodes as "don't cache" which means function iput_final will evict them immediately, allowing us to properly recover the journal on other cluster nodes.
