Message-Id: <20240402154842.508032-7-eugen.hristev@collabora.com> Date: Tue, 2 Apr 2024 18:48:39 +0300 From: Eugen Hristev <eugen.hristev@...labora.com> To: tytso@....edu, adilger.kernel@...ger.ca, linux-ext4@...r.kernel.org, jaegeuk@...nel.org, chao@...nel.org, linux-f2fs-devel@...ts.sourceforge.net, linux-fsdevel@...r.kernel.org Cc: linux-kernel@...r.kernel.org, kernel@...labora.com, eugen.hristev@...labora.com, viro@...iv.linux.org.uk, brauner@...nel.org, jack@...e.cz, krisman@...e.de, Gabriel Krisman Bertazi <krisman@...labora.com> Subject: [PATCH v15 6/9] ext4: Log error when lookup of encoded dentry fails From: Gabriel Krisman Bertazi <krisman@...labora.com> 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.
