| |
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Trond Myklebust <Trond.Myklebust@netapp.com>
commit fb13bfa7e1bcfdcfdece47c24b62f1a1cad957e9 upstream.
If a file OPEN is denied due to a share lock, the resulting NFS4ERR_SHARE_DENIED is currently mapped to the default EIO. This patch adds a more appropriate mapping, and brings Linux into line with what Solaris 10 does.
