NFSv4.1: nfs4_fl_prepare_ds must be careful about reporting success.

2017-03-16T02:26:38Z

commit cfd278c280f997cf2fe4662e0acab0fe465f637b upstream. Various places assume that if nfs4_fl_prepare_ds() turns a non-NULL 'ds', then ds->ds_clp will also be non-NULL. This is not necessasrily true in the case when the process received a fatal signal while nfs4_pnfs_ds_connect is waiting in nfs4_wait_ds_connect(). In that case ->ds_clp may not be set, and the devid may not recently have been marked unavailable. So add a test for ds_clp == NULL and return NULL in that case.

NFSv4: Ensure that we call FREE_STATEID when NFSv4.x stateids are revoked

2014-11-27T11:21:46Z

commit c606bb8857921d3ecf4d353942d6cc7e116cc75a upstream. NFSv4.x (x>0) requires us to call TEST_STATEID+FREE_STATEID if a stateid is revoked. We will currently fail to do this if the stateid is a delegation. http://lkml.kernel.org/r/CAN-5tyHwG=Cn2Q9KsHWadewjpTTy_K26ee+UnSvHvG4192p-Xw@mail.gmail.com Signed-off-by: Trond Myklebust Signed-off-by: Luis Henriques

nfs: merge nfs_pgio_data into _header

2014-10-05T20:41:00Z

commit d45f60c67848b9f19160692581d78e5b4757a000 upstream. struct nfs_pgio_data only exists as a member of nfs_pgio_header, but is passed around everywhere, because there used to be multiple _data structs per _header. Many of these functions then use the _data to find a pointer to the _header. This patch cleans this up by merging the nfs_pgio_data structure into nfs_pgio_header and passing nfs_pgio_header around instead.

Pull NFS client updates from Trond Myklebust: "Highlights include: - massive cleanup of the NFS read/write code by Anna and Dros - support multiple NFS read/write requests per page in order to deal with non-page aligned pNFS striping. Also cleans up the r/wsize < page size code nicely. - stable fix for ensuring inode is declared uptodate only after all the attributes have been checked. - stable fix for a kernel Oops when remounting - NFS over RDMA client fixes - move the pNFS files layout driver into its own subdirectory" * tag 'nfs-for-3.16-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (79 commits) NFS: populate ->net in mount data when remounting pnfs: fix lockup caused by pnfs_generic_pg_test NFSv4.1: Fix typo in dprintk NFSv4.1: Comment is now wrong and redundant to code NFS: Use raw_write_seqcount_begin/end int nfs4_reclaim_open_state xprtrdma: Disconnect on registration failure xprtrdma: Remove BUG_ON() call sites xprtrdma: Avoid deadlock when credit window is reset SUNRPC: Move congestion window constants to header file xprtrdma: Reset connection timeout after successful reconnect xprtrdma: Use macros for reconnection timeout constants xprtrdma: Allocate missing pagelist xprtrdma: Remove Tavor MTU setting xprtrdma: Ensure ia->ri_id->qp is not NULL when reconnecting xprtrdma: Reduce the number of hardway buffer allocations xprtrdma: Limit work done by completion handler xprtrmda: Reduce calls to ib_poll_cq() in completion handlers xprtrmda: Reduce lock contention in completion handlers xprtrdma: Split the completion queue xprtrdma: Make rpcrdma_ep_destroy() return void ...

NFSv4.1: Comment is now wrong and redundant to code

2014-06-09T13:54:29Z

The save of the write offset was removed some time ago, so that part of the comment is bogus. The remainder is pretty self-evident. So off with it! Signed-off-by: Tom Haynes Signed-off-by: Trond Myklebust

Push the file layout driver into a subdirectory

2014-05-30T00:21:56Z

The object and block layouts already exist in their own subdirectories. This patch completes the set! Note that as a layout denotes nfs4 already, I stripped that prefix out of the file names. Signed-off-by: Tom Haynes Acked-by: Jeff Layton Signed-off-by: Trond Myklebust
