mav@ has found that NFS servers exporting ZFS file systems
can perform better when using a 128K read/write data size.
This patch changes NFS_MAXDATA from 64K to 128K so that
clients can use 128K for NFS mounts to allow this.
The patch also renames NFS_MAXDATA to NFS_SRVMAXIO so
that it is clear that it applies to the NFS server side
only. It also avoids a name conflict with the NFS_MAXDATA
defined in rpcsvc/nfs_prot.h, that is used for userland RPC.
File systems that do not use the buffer cache (such as ZFS) must
use VOP_FSYNC() to perform the NFS server's Commit operation.
This patch adds a mnt_kern_flag called MNTK_USES_BCACHE which
is set by file systems that use the buffer cache. If this flag
is not set, the NFS server always does a VOP_FSYNC().
This should be ok for old file system modules that do not set
MNTK_USES_BCACHE, since calling VOP_FSYNC() is correct, although
it might not be optimal for file systems that use the buffer cache.
Allow additional flags to be passed to netstat -i in the daily status check.
In particular, this allows an administrator to specify "-h" for human
readable output if that is preferred.
The default setting passes "-d", so that can be excluded by using a custom
setting.
This update brings few features:
o Support for the setmaster/dropmaster ioctls. For instance, they
are used to run multiple X servers simultaneously.
o Support for minor devices. The only user-visible change is a new
entry in /dev/dri but it is useless at the moment. This is a
first step to support render nodes [1].
The main benefit is to greatly reduce the diff with Linux (at the
expense of an unreadable commit diff). Hopefully, next upgrades will be
easier.
No updates were made to the drivers, beside adapting them to API
changes.

drm: Sort connector modes based on vrefresh
Keeping the modes sorted by vrefresh before the pixel clock makes the
mode list somehow more pleasing to the eye.

r280299 (cperciva):
When creating VM images, copy the contents of the created filesystem
into a new filesystem before packaging it into a disk image. This
prevents "remnants" of deleted files from showing up in the VM images,
and reduces their compressed size (by about 10% for the cloudware
images) as a result.
r280840 (cperciva):
Clean up filesystem unmounting in vmimage builds:
- Remove vm_umount_base function which is currently unused.
- Add umount_loop function which loops attempting to unmount one
filesystem.
- Replace calls to umount with calls to umount_loop.
- Don't attempt to unmount ${DESTDIR}/dev if it isn't mounted.
The looping is necessary because sometimes umount fails due to
filesystems being busy. The most common cause of such busyness is
periodic(8) jobs running `find / ...`.

Improve check for whether ${DESTDIR}/dev is mounted.

r281783:
When building VM disk images, vm_copy_base() uses tar(1) to copy
the userland from one md(4)-mounted filesystem to a clean filesystem
to prevent remnants of files that were added and removed from
resulting in an unclean filesystem. When newfs(8) creates the first
filesystem with journaled soft-updates enabled, the /.sujournal file
in the new filesystem cannot be overwritten by the /.sujournal in the
original filesystem.
To avoid this particular error case, do not enable journaled
soft-updates when creating the md(4)-backed filesystems, and instead
use tunefs(8) to enable journaled soft-updates after the new
filesystem is populated in vm_copy_base().
While here, fix a long standing bug where the build environment /boot
files were used by mkimg(1) when creating the VM disk images by using
the files in .OBJDIR.

Add config option PAE_TABLES for the i386 kernel. It switches pmap to
use PAE format for the page tables, but does not incur other
consequences of the full PAE config. In particular, vm_paddr_t and
bus_addr_t are left 32bit, and max supported memory is still limited
by 4GB.
The option allows to have nx permissions for memory mappings on i386
kernel, while keeping the usual i386 KBI and avoiding the kernel data
sizing problems typical for the PAE config.

- Move the aio(4) checks to a single function (aio_available); use modfind(2)
instead of depending on SIGSYS (doesn't work when aio(4) support is missing,
not documented in the aio syscall manpages).
