Subject: [PATCH 6.12.y 3/8] afs: Drop the net parameter from afs_unuse_cell()
Date: Wed, 29 Jul 2026 21:02:03 -0400 [thread overview]
Message-ID: <20260730010208.1700694-3-sashal@kernel.org> (raw)
In-Reply-To: <20260730010208.1700694-1-sashal@kernel.org>
From: David Howells <dhowells@redhat.com>
[ Upstream commit 469c82b558628482002e4819d35b7670f0a989fd ]
Remove the redundant net parameter to afs_unuse_cell() as cell->net can be
used instead.
