Bruce Fields" Subject: pNFS read/write behavior change in 2.6.39 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Sender: linux-nfs-owner@vger.kernel.org List-ID: MIME-Version: 1.0 I run 2.6.39-0.rc4.git2.0 build for fedora-16 build by redhat. Probably Steve and Bruce can comment on the patch set. My observation is that state id provided by client on read to DS dit not contain correct stateid: struct stateid4 { uint32_t seqid; opaque other[12]; }; The seqid equals to zero when client send it to DS which is not the value returned on OPEN. The problem is not observed with ae7441fa120ff35b40b4dab167645907a9da1dab from Bennys tree as well as with frdora 15 builds from Steve. With Regards, Tigran.
