Date: Thu, 28 Apr 2022 18:10:25 -0400 From: Gabriel Krisman Bertazi <krisman@...labora.com> To: tytso@....edu, adilger.kernel@...ger.ca, jaegeuk@...nel.org Cc: linux-ext4@...r.kernel.org, linux-f2fs-devel@...ts.sourceforge.net, ebiggers@...nel.org, Gabriel Krisman Bertazi <krisman@...labora.com>, kernel@...labora.com Subject: [PATCH v2 5/7] ext4: Log error when lookup of encoded dentry fails If the volume is in strict mode, ext4_ci_compare can report a broken encoding name. This will not trigger on a bad lookup, which is caught earlier, only if the actual disk name is bad.
