| H A D | namei.h | c2fd68b6 Tue Jul 27 05:48:40 CDT 2021 Christian Brauner <christian.brauner@ubuntu.com> namei: add mapping aware lookup helper
Various filesystems rely on the lookup_one_len() helper to lookup a
single path component relative to a well-known starting point. Allow
such filesystems to support idmapped mounts by adding a version of this
helper to take the idmap into account when calling inode_permission().
This change is a required to let btrfs (and other filesystems) support
idmapped mounts.
