Unlike the previous attempt, this takes into account the fact that we may be calling it from the recovery thread itself. Detect this by looking at what kind of open we're doing, and checking the state of the NFS_DELEGATION_NEED_RECLAIM if it turns out we're doing a reboot reclaim-type open.

Change the uniform client string generator to dynamically allocate the NFSv4 client name string buffer. With this patch, we can eliminate the buffers that are embedded within the "args" structs and simply use the name string that is hanging off the client. This uniform string case is a little simpler than the nonuniform since we don't need to deal with RCU, but we do have two different cases, depending on whether there is a uniquifier or not.

...instead of buffers that are part of their arg structs. We already hold a reference to the client, so we might as well use the allocated buffer. In the event that we can't allocate the clp->cl_owner_id, then just return -ENOMEM. Note too that we switch from a GFP_KERNEL allocation here to GFP_NOFS. It's possible we could end up trying to do a SETCLIENTID or EXCHANGE_ID in order to reclaim some memory, and the GFP_KERNEL allocations in the existing code could cause recursion back into NFS reclaim.

The current buffer is much too small if you have a relatively long hostname. Bring it up to the size of the one that SETCLIENTID has.

This patch adds a GETATTR to the end of ALLOCATE and DEALLOCATE operations so we can set the updated inode size and change attribute directly. DEALLOCATE will still need to release pagecache pages, so nfs42_proc_deallocate() now calls truncate_pagecache_range() before contacting the server.

If we're using NFSv4.1, then we have the ability to let the server know whether or not we believe that returning a delegation as part of our OPEN request would be useful. The feature needs to be used with care, since the client sending the request doesn't necessarily know how other clients are using that file, and how they may be affected by the delegation. For this reason, our initial use of the feature will be to let the server know when the client believes that handing out a delegation would not be useful. The first application for this function is when opening the file using O_DIRECT. Signed-off-by: NTrond Myklebust <trond.myklebust@primarydata.com>

This patch adds mirrored write support to the pgio layer. The default is to use one mirror, but pgio callers may define callbacks to change this to any value up to the (arbitrarily selected) limit of 16. The basic idea is to break out members of nfs_pageio_descriptor that cannot be shared between mirrored DSes and put them in a new structure.

For pNFS direct writes, layout driver may dynamically allocate ds_cinfo.buckets. So we need to take care to free them when freeing dreq. Ideally this needs to be done inside layout driver where ds_cinfo.buckets are allocated. But buckets are attached to dreq and reused across LD IO iterations. So I feel it's OK to free them in the generic layer.

Currently asynchronous NFSv4 request will be retried with exponential timeout (from 1/10 to 15 seconds), but async requests will always use a 15second retry. Some "async" requests are really synchronous though. The async mechanism is used to allow the request to continue if the requesting process is killed. In those cases, an exponential retry is appropriate. For example, if two different clients both open a file and get a READ delegation, and one client then unlinks the file (while still holding an open file descriptor), that unlink will used the "silly-rename" handling which is async. The first rename will result in NFS4ERR_DELAY while the delegation is reclaimed from the other client. The rename will not be retried for 15 seconds, causing an unlink to take 15 seconds rather than 100msec. This patch only added exponential timeout for async unlink and async rename. Other async calls, such as 'close' are sometimes waited for so they might benefit from exponential timeout too.

Currently there is no XDR buffer space allocated for the per-layout driver layoutcommit payload, which leads to server buffer overflows in the blocklayout driver even under simple workloads.

The current CB_COMPOUND handling code tries to compare the principal name of the request with the cl_hostname in the client. This is not guaranteed to ever work, particularly if the client happened to mount a CNAME of the server or a non-fqdn. Fix this by instead comparing the cr_principal string with the acceptor name that we get from gssd. In the event that gssd didn't send one down (i.e. it was too old), then we fall back to trying to use the cl_hostname as we do today.
