vfs.nfsd.nfsd_enable_stringtouid, but in reverse - when set to 1,
it forces the NFSv4 server to return numeric UIDs and GIDs instead
of "user@domain" strings. This helps with clients that can't
translate returned identifiers, eg when rerooting.
The same can be achieved by just never running nfsuserd(8),
but the sysctl is useful to toggle the behaviour back and forth
without rebooting.

https://www.illumos.org/issues/3306
The upstream change was made before we started to import upstream commits
individually. It was imported into the illumos vendor area as r242733.
That commit was MFV-ed in r260138, but as the commit message says
vdev_file.c was left intact.
This commit actually implements the parallel I/O for vdev_file using a
taskqueue with multiple thread. This implementation does not depend on
the illumos or FreeBSD bio interface at all, but uses zio_t to pass
around all the relevent data. So, the code looks a bit different from
the upstream.
This commit also incorporates ZoL commit
zfsonlinux/zfs/bc25c9325b0e5ced897b9820dad239539d561ec9 that fixed
https://github.com/zfsonlinux/zfs/issues/2270
We need to use a dedicated taskqueue for exactly the same reason as ZoL
as we do not implement TASKQ_DYNAMIC.

AKA Make time_t 64 bits on powerpc(32).
PowerPC currently (until now) was one of two architectures with a 32-bit time_t
on 32-bit archs (the other being i386). This is an ABI breakage, so all ports,
and all local binaries, *must* be recompiled.

A NFSv4.1/pNFS server using File Layout can specify that Commit operations
are to be done against the DS instead of MDS. Since no extant pNFS
server did this, the code was untested and "#ifdef notyet".
The FreeBSD pNFS server I am developing does specify that Commits be done
through the DS, so the code has been enabled/tested.
This patch should only affect the case of a pNFS server that specfies
Commits through the DS.

the requested protection.
The syscall returns success without changing the protection of the
guard. This is consistent with the current mprotect(2) behaviour on
the unmapped ranges. More important, the calls performed by libc and
libthr to allow execution of stacks, if requested by the loaded ELF
objects, do the expected change instead of failing on the grow space
guard.

If CDPATH is used non-trivially or the operand is "-", cd writes the
directory actually switched to. (We currently do this only in interactive
shells, but POSIX requires this in non-interactive shells as well.)
As mentioned in Austin group bug #1045, cd shall not return an error while
leaving the current directory changed. Therefore, ignore any write error.
If mmap(2) is called with the MAP_STACK flag and the size which is
less or equal to the initial stack mapping size plus guard,
calculation of the mapping layout created zero-sized guard. Attempt
to create such entry failed in vm_map_insert(), causing the whole
mmap(2) call to fail.
Fix it by adjusting the initial mapping size to have space for
non-empty guard. Reject MAP_STACK requests which are shorter or equal
to the configured guard pages size.

fixed size for the name buffer PFS_NAMELEN.
As r318736 was commited (ino64 project) the size of the permanent part
of the struct dirent was changed, so calulate PFS_DELEN properly.
We set the shareability attributes in TCR_EL1 on boot. These tell the
hardware the pagetables are in cached memory so there is no need to flush
the entries from the cache to memory.
This has about 4.2% improvement in system time and 2.7% improvement in
user time for a buildkernel -j48 on a ThunderX.
Keep the old code for now to allow for further comparisons.
It distinguishes between data flow sockets and listening sockets, and
in case of the latter doesn't change resource limits, since listening
sockets don't hold any buffers, they only carry values to be inherited
by their children.
When the NFSv4.1 client is doing pNFS, it needs to get an Open and
a Layout for every file it will be doing I/O on. The current code
does two separate RPCs to get these. This patch adds two new compounds
that do the both the Open and LayoutGet in the same RPC, reducing the
RPC count.
It also factors out the code that sets up and parses the LayoutGet operation
into separate functions, so that the code doesn't get duplicated for
these new RPCs.
This patch is fairly large, but should only affect the NFSv4.1 client
when the "pnfs" option is specified.
