From 1f58bb18f6f28d1df0b7144d90bc90ee5672416d Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 20 May 2019 13:44:57 +0100 Subject: mount_pseudo(): drop 'name' argument, switch to d_make_root() Once upon a time we used to set ->d_name of e.g. pipefs root so that d_path() on pipes would work. These days it's completely pointless - dentries of pipes are not even connected to pipefs root. However, mount_pseudo() had set the root dentry name (passed as the second argument) and callers kept inventing names to pass to it. Including those that didn't *have* any non-root dentries to start with... All of that had been pointless for about 8 years now; it's time to get rid of that cargo-culting...

This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information.
