Message-ID: <20240111225816.18117-9-krisman@suse.de> Date: Thu, 11 Jan 2024 19:58:14 -0300 From: Gabriel Krisman Bertazi <krisman@...e.de> To: viro@...iv.linux.org.uk, ebiggers@...nel.org, jaegeuk@...nel.org, tytso@....edu Cc: linux-f2fs-devel@...ts.sourceforge.net, linux-ext4@...r.kernel.org, linux-fsdevel@...r.kernel.org, amir73il@...il.com, Gabriel Krisman Bertazi <krisman@...e.de> Subject: [PATCH v3 08/10] f2fs: Configure dentry operations at dentry-creation time This was already the case for case-insensitive before commit bb9cd9106b22 ("fscrypt: Have filesystems handle their d_ops"), but it was changed to set at lookup-time to facilitate the integration with fscrypt. But it's a problem because dentries that don't get created through ->lookup() won't have any visibility of the operations. Since fscrypt now also supports configuring dentry operations at creation-time, do it for any encrypted and/or casefold volume, simplifying the implementation across these features.
