Subject: [PATCH v6 06/15] cifs: Move cifs_loose_read_iter() and cifs_file_write_iter() to file.c
Date: Thu, 28 Mar 2024 16:57:57 +0000 [thread overview]
Message-ID: <20240328165845.2782259-7-dhowells@redhat.com> (raw)
In-Reply-To: <20240328165845.2782259-1-dhowells@redhat.com>
Move cifs_loose_read_iter() and cifs_file_write_iter() to file.c so that
they are colocated with similar functions rather than being split with
cifsfs.c.
