Subject: [PATCH 1/2] pnfs: fix-multiple-free-slot-calls
Date: Thu, 22 Oct 2009 09:15:42 -0400	[thread overview]
Message-ID: <1256217343-6991-2-git-send-email-andros@netapp.com> (raw)
In-Reply-To: <1256217343-6991-1-git-send-email-andros@netapp.com>

From: Andy Adamson <andros@netapp.com>

Use _nfs4_async_handle_error and pass in either the MDS or DS client

Reported-by: Trond Myklebust <trond.myklebust@netapp.com>

nfs41_sequence_free_slot is called multiple times on SEQUENCE operation errors.

Fix this by moving the call to nfs41_sequence_free_slot from the error path of
nfs41_sequence_done to nfs4_async_handle_error for the SEQUENCE operation
error cases.
