Subject: [PATCH 1/8] fs/configfs: rework configfs_is_root()
Date: Sat, 13 Jun 2026 13:14:30 +0200 [thread overview]
Message-ID: <20260613111437.101763-2-hare@kernel.org> (raw)
In-Reply-To: <20260613111437.101763-1-hare@kernel.org>
From: Hannes Reinecke <hare@suse.de>
configfs_is_root() should not check for static structures, but
use the information in the structure itself.
