NFSv4.1/pNFS: Don't queue up a new commit if the layout segment is invalid

2015-12-31T20:55:35+00:00

If the layout segment is invalid, then we should not be adding more write requests to the commit list. Instead, those writes should be replayed after requesting a new layout. Signed-off-by: Trond Myklebust

NFS: Allow multiple commit requests in flight per file

2015-12-31T18:53:48+00:00

Allow synchronous RPC calls to wait for pending RPC calls to finish, but also allow asynchronous ones to just fire off another commit. With this patch, the xfstests generic/074 test completes in 226s instead of 242s Signed-off-by: Trond Myklebust

NFS/pNFS: Fix up pNFS write reschedule layering violations and bugs

2015-12-31T18:50:42+00:00

The flexfiles layout in particular, seems to want to poke around in the O_DIRECT flags when retransmitting. This patch sets up an interface to allow it to call back into O_DIRECT to handle retransmission correctly. It also fixes a potential bug whereby we could change the behaviour of O_DIRECT if an error is already pending. Signed-off-by: Trond Myklebust

pNFS: Add flag to track if we've called nfs4_ff_layout_stat_io_start_read/write

nfs: use sliding delay when LAYOUTGET gets NFS4ERR_DELAY

2015-11-24T02:57:44+00:00

When LAYOUTGET gets NFS4ERR_DELAY, we currently will wait 15s before retrying the call. That is a _very_ long time, so add a timeout value to struct nfs4_layoutget and pass nfs4_async_handle_error a pointer to it. This allows the RPC engine to use a sliding delay window, instead of a 15s delay. Signed-off-by: Jeff Layton Signed-off-by: Trond Myklebust

nfs: Remove unused xdr page offsets in getacl/setacl arguments

2015-11-03T17:33:01+00:00

The arguments passed around for getacl and setacl xdr encoding, struct nfs_setaclargs and struct nfs_getaclargs, both contain an array of pages, an offset into the first page, and the length of the page data. The offset is unused as it is always zero; remove it. Signed-off-by: Andreas Gruenbacher Signed-off-by: Trond Myklebust
