Subject: [PATCH 14/40] REVERT: pnfs_submit: update nfs4_async_handle_error for data server
Date: Fri, 4 Feb 2011 16:33:36 -0500 [thread overview]
Message-ID: <1296855242-2592-15-git-send-email-andros@netapp.com> (raw)
In-Reply-To: <1296855242-2592-14-git-send-email-andros@netapp.com>
From: Andy Adamson <andros@netapp.com>
Except for is_ds_only_session declaration
Layout drivers will declare their own handlers for async i/o.
