alloc_pages_bulk_array() attempts to allocate at least one page based on
the provided pages, and then opportunistically allocates more if that
can be done without dropping the spinlock.
So if it returns fewer than requested, that could just mean that it
needed to drop the lock. In that case, try again immediately.
Only pause for a time if no progress could be made.

In the reexport case, nfsd is currently passing along locks with the
reclaim bit set. The client sends a new lock request, which is granted
if there's currently no conflict--even if it's possible a conflicting
lock could have been briefly held in the interim.
We don't currently have any way to safely grant reclaim, so for now
let's just deny them all.
I'm doing this by passing the reclaim bit to nfs and letting it fail the
call, with the idea that eventually the client might be able to do
something more forgiving here.

As in the v4 case, it doesn't work well to block waiting for a lock on
an nfs filesystem.
As in the v4 case, that means we're depending on the client to poll.
It's probably incorrect to depend on that, but I *think* clients do poll
in practice. In any case, it's an improvement over hanging the lockd
thread indefinitely as we currently are.

NFS implements blocking locks by blocking inside its lock method. In
the reexport case, this blocks the nfs server thread, which could lead
to deadlocks since an nfs server thread might be required to unlock the
conflicting lock. It also causes a crash, since the nfs server thread
assumes it can free the lock when its lm_notify lock callback is called.
Ideal would be to make the nfs lock method return without blocking in
this case, but for now it works just not to attempt blocking locks. The
difference is just that the original client will have to poll (as it
does in the v4.0 case) instead of getting a callback when the lock's
available.

Locks have two sets of op arrays, fl_lmops for the lock manager (lockd
or nfsd), fl_ops for the filesystem. The server-side lockd code has
been setting its own fl_ops, which leads to confusion (and crashes) in
the reexport case, where the filesystem expects to be the only one
setting fl_ops.
And there's no reason for it that I can see-the lm_get/put_owner ops do
the same job.

Disconnect injection stress-tests the ability for both client and
server implementations to behave resiliently in the face of network
instability.
A file called /sys/kernel/debug/fail_sunrpc/ignore-server-disconnect

while allowing other types of sunrpc errors to be injected. The
default setting is that server-side disconnect injection is enabled

/proc/lock_stat indicates the the sc_send_lock is heavily
contended when the server is under load from a single client.
To address this, convert the send_ctxt free list to an llist.
Returning an item to the send_ctxt cache is now waitless, which
reduces the instruction path length in the single-threaded Send
handler (svc_rdma_wc_send).
The goal is to enable the ib_comp_wq worker to handle a higher

Because wake_up() takes an IRQ-safe lock, it can be expensive,
especially to call inside of a single-threaded completion handler.
What's more, the Send wait queue almost never has waiters, so
most of the time, this is an expensive no-op.

There's a few cases that a string that is to be recorded in a trace event,
does not have a terminating 'nul' character, and instead, the tracepoint
passes in the length of the string to record.
Add two helper macros to the trace event code that lets this work easier,
than tricks with "%.*s" logic.
__string_len() which is similar to __string() for declaration, but takes a
length argument.
__assign_str_len() which is similar to __assign_str() for assiging the
string, but it too takes a length argument.
Note, the TRACE_EVENT() macro will allocate the location on the ring
buffer to 'len + 1', that will be used to store the string into. It is a
requirement that the 'len' used for this is a most the length of the
string being recorded.
This string can still use __get_str() just like strings created with
__string() can use to retrieve the string.

Replacing a page in rq_pages[] requires a get_page(), which is a
bus-locked operation, and a put_page(), which can be even more
costly.
To reduce the cost of replacing a page in rq_pages[], batch the
put_page() operations by collecting "freed" pages in a pagevec,
and then release those pages when the pagevec is full. This
pagevec is also emptied when each RPC completes.

A few useful observations:
- The value in @size is never modified.
- splice_desc.len is an unsigned int, and so is xdr_buf.page_len.
An implicit cast to size_t is unnecessary.
- The computation of .page_len is the same in all three arms
of the "if" statement, so hoist it out to make it clear that
the operation is an unconditional invariant.
The resulting function is 18 bytes shorter on my system (-Os).
