NFS: NFSoRDMA Client Changes

* bugfixes:
NFSv4: Return delegations synchronously in evict_inode
SUNRPC: Fix a regression when reconnecting
NFS: remount with security change should return EINVAL
nfs: do not export discarded symbols
NFSv4.1: don't export static symbol
The brand new GCC 5.1.0 warns by default on using a boolean in the
switch condition. This results in the following warning:
fs/nfs/nfs4proc.c: In function 'nfs4_proc_get_rootfh':
fs/nfs/nfs4proc.c:3100:10: warning: switch condition has boolean value [-Wswitch-bool]
switch (auth_probe) {
^
This code was obviously using switch to make use of the fall-through
semantics (without the usual comment, though).
Rewrite that code using if statements to avoid the warning and make
the code a bit more readable on the way.

This reverts commit 5a254d08b0.
Since commit 5a254d08b0 ("nfs: replace nfs_add_stats with
nfs_inc_stats when add one"), nfs_readpage and nfs_do_writepage use
nfs_inc_stats to increment NFSIOS_READPAGES and NFSIOS_WRITEPAGES
instead of nfs_add_stats.
However nfs_inc_stats does not do the same thing as nfs_add_stats with
value 1 because these functions work on distinct stats:
nfs_inc_stats increments stats from "enum nfs_stat_eventcounters" (in
server->io_stats->events) and nfs_add_stats those from "enum
nfs_stat_bytecounters" (in server->io_stats->bytes).

For direct read that has IO size larger than rsize, we'll split
it into several READ requests and nfs_direct_good_bytes() would
count completed bytes incorrectly by eating last zero count reply.
Fix it by handling mirror and non-mirror cases differently such that
we only count mirrored writes differently.

2ef47eb1 (NFS: Fix use of nfs_attr_use_mounted_on_fileid()) was a good
start to fixing a circular directory structure warning for NFS v4
"junctioned" mountpoints. Unfortunately, further testing continued to
generate this error.
My server is configured like this:
anna@nfsd ~ % df
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 9.1G 2.0G 6.5G 24% /
/dev/vdc1 1014M 33M 982M 4% /exports

/exports/vol1/ *(rw,async,no_subtree_check,no_root_squash)
/exports/vol1/vol2 *(rw,async,no_subtree_check,no_root_squash)
I've been running chown across the entire mountpoint twice in a row to
hit this problem. The first run succeeds, but the second one fails with
the circular directory warning along with:
anna@client ~ % dmesg
[Apr 3 14:28] NFS: server 192.168.100.204 error: fileid changed

WHere 0x80 is the mountpoint's fileid and 0x100080 is the mounted-on
fileid.
This patch fixes the issue by requesting an updated mounted-on fileid
from the server during nfs_update_inode(), and then checking that the
fileid stored in the nfs_inode matches either the fileid or mounted-on
fileid returned by the server.

v2: gracefully handle the case where some dentry pointers end up NULL
and be more dilligent about zeroing out dentry pointers
We currently have a problem that SELinux policy is being enforced when
creating debugfs files. If a debugfs file is created as a side effect of
doing some syscall, then that creation can fail if the SELinux policy
for that process prevents it.
This seems wrong. We don't do that for files under /proc, for instance,
so Bruce has proposed a patch to fix that.
While discussing that patch however, Greg K.H. stated:
"No kernel code should care / fail if a debugfs function fails, so
please fix up the sunrpc code first."
This patch converts all of the sunrpc debugfs setup code to be void
return functins, and the callers to not look for errors from those
functions.
This should allow rpc_clnt and rpc_xprt creation to work, even if the
kernel fails to create debugfs files for some reason.

Chuck pointed out a problem that crept in with commit 6ffa30d3f7 (nfs:
don't call blocking operations while !TASK_RUNNING). Linux counts tasks
in uninterruptible sleep against the load average, so this caused the
system's load average to be pinned at at least 1 when there was a
NFSv4.1+ mount active.
Not a huge problem, but it's probably worth fixing before we get too
many complaints about it. This patch converts the code back to use
TASK_INTERRUPTIBLE sleep, simply has it flush any signals on each loop
iteration. In practice no one should really be signalling this thread at
all, so I think this is reasonably safe.
With this change, there's also no need to game the hung task watchdog so
we can also convert the schedule_timeout call back to a normal schedule.

The RPC/RDMA transport's FRWR registration logic registers whole
pages. This means areas in the first and last pages that are not
involved in the RDMA I/O are needlessly exposed to the server.
Buffered I/O is typically page-aligned, so not a problem there. But
for direct I/O, which can be byte-aligned, and for reply chunks,
which are nearly always smaller than a page, the transport could
expose memory outside the I/O buffer.
FRWR allows byte-aligned memory registration, so let's use it as
it was intended.

chunk list when an RPC/RDMA request is retransmitted.
Note that rpc_xdr_encode() resets and re-encodes the entire RPC
send buffer for each retransmit of an RPC. The RPC send buffer
is not preserved from the previous transmission of an RPC.
Revert 6ab59945f2, and instead, just force each request to be
fully marshaled every time through ->send_request. This should
preserve the fix from 6ab59945f2, while also performing pullup

Merge tag 'fixes-v4.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Fixes for omaps for the -rc cycle:
- Fix a device tree based booting vs legacy booting regression for
omap3 crypto hardware by adding the missing DMA channels.
- Fix /sys/bus/soc/devices/soc0/family for am33xx devices.
- Fix two timer issues that can cause hangs if the timer related
hwmod data is missing like it often initially is for new SoCs.
- Remove pcie hwmods entry from dts as that causes runtime PM to
fail for the PHYs.
- A paper bag type dts configuration fix for dm816x GPIO
interrupts that I just noticed. This is most of the changes
diffstat wise, but as it's a basic feature for connecting
devices and things work otherwise, it should be fixed.

The UART reference clock speed is 7273.8 kHz, not 72738 kHz.
Dots aren't usually used in node names even though ePAPR permits
them. However, this can easily be avoided by expressing the
frequency in Hz, not kHz.
This patch changes the name to refclk7273800hz, reflecting the
actual clock speed.

There are only 2 fixes, one for the zeus board about the regulator changes,
where a typo prevented the zeus board from having a working can regulator,
and one regression triggered by the interrupts IRQ shift of 16 affecting all
boards.
