Subject: [PATCH v5 04/14] ceph: pass an idmapping to mknod/symlink/mkdir/rename
Date: Thu, 8 Jun 2023 17:42:45 +0200 [thread overview]
Message-ID: <20230608154256.562906-5-aleksandr.mikhalitsyn@canonical.com> (raw)
In-Reply-To: <20230608154256.562906-1-aleksandr.mikhalitsyn@canonical.com>
From: Christian Brauner <christian.brauner@ubuntu.com>
Enable mknod/symlink/mkdir/rename iops to handle idmapped mounts.
This is just a matter of passing down the mount's idmapping.
