Subject: [PATCH v12 26/54] ceph: pass the request to parse_reply_info_readdir()
Date: Thu, 31 Mar 2022 11:31:02 -0400 [thread overview]
Message-ID: <20220331153130.41287-27-jlayton@kernel.org> (raw)
In-Reply-To: <20220331153130.41287-1-jlayton@kernel.org>
From: Xiubo Li <xiubli@redhat.com>
Instead of passing just the r_reply_info to the readdir reply parser,
pass the request pointer directly instead. This will facilitate
implementing readdir on fscrypted directories.
