From e28c02b94f9e039beeb5c75198caf6e17b66c520 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Thu, 30 Jul 2020 12:31:38 -0500 Subject: [PATCH] gfs2: When gfs2_dirty_inode gets a glock error, dump the glock Before this patch, if function gfs2_dirty_inode got an error when trying to lock the inode glock, it complained, but it didn't say what glock or inode had the problem. In this case, it almost always means that dinode_in found an error with the dinode in the file system. So it makes sense to dump the glock, which tells us the location of the dinode in the file system. That will allow us to analyze the corruption from the metadata.
