Subject: [PATCH v2 04/13] ceph: allow idmapped mknod inode op
Date: Wed, 24 May 2023 17:33:06 +0200	[thread overview]
Message-ID: <20230524153316.476973-5-aleksandr.mikhalitsyn@canonical.com> (raw)
In-Reply-To: <20230524153316.476973-1-aleksandr.mikhalitsyn@canonical.com>

From: Christian Brauner <christian.brauner@ubuntu.com>

passing down the mount's idmapping.
