Eventually, I'd like to invoke rpcrdma_create_req() during the
call_reserve step. Memory allocation there probably needs to use
GFP_NOIO. Therefore a set of GFP flags needs to be passed in.
As an additional clean up, just return a pointer or NULL, because
the only error return code here is -ENOMEM.

If the server is unable to immediately execute an RPC call, and returns
an NFS4ERR_DELAY then we can assume it is safe to interrupt the operation
in order to handle ordinary signals. This allows the application to
service timer interrupts that would otherwise have to wait until the
server is again able to respond.

When the client is reading or writing using pNFS, and hits an error
on the DS, then it typically sends a LAYOUTERROR and/or LAYOUTRETURN
to the MDS, before redirtying the failed pages, and going for a new
round of reads/writebacks. The problem is that if the server has no
way to fix the DS, then we may need a way to interrupt this loop
after a set number of attempts have been made.
This patch adds an optional module parameter that allows the admin
to specify how many times to retry the read/writeback process before
failing with a fatal error.
The default behaviour is to retry forever.

When calculating the major timeout for a new task, when we know that the

If a soft NFSv4 request is sent, then we don't need it to time out unless
the connection breaks. The reason is that as long as the connection is
unbroken, the protocol states that the server is not allowed to drop the

assume that all transmitted RPC requests are being processed by the server,
and that retransmissions and timeouts of those requests are unwarranted.

resolve a problem in the sh-sci driver.
Note, the second patch for build warning fix for the sc16is7xx driver

unlike all of the other patches, but it has passed 0-day testing and
everyone seems to agree that it is correct.

Merge tag 'tty-5.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial fixes from Greg KH:
"Here are five small fixes for some tty/serial/vt issues that have been
reported.
The vt one has been around for a while, it is good to finally get that
resolved. The others fix a build warning that showed up in 5.1-rc1,
and resolve a problem in the sh-sci driver.
Note, the second patch for build warning fix for the sc16is7xx driver
was just applied to the tree, as it resolves a problem with the
previous patch to try to solve the issue. It has not shown up in
linux-next yet, unlike all of the other patches, but it has passed
0-day testing and everyone seems to agree that it is correct"
