error is returned all the way back to the dtrace app, it's hard to
figure out where that error came from.
Add a couple of functions to get and set the error location which can
be optionally compiled into the library.
* Handle the different ioctl design.
* Support the freopen() changes.
* Use functions in FreeBSD's process library rather than the CDDL
library that Solaris has which sits on top of their process file
system and is therefore unsuitable for use on FreeBSD. The libproc
API for FreeBSD is deliberately different to that on Solaris because
Sun wouldn't release the libproc.h header under a BSD license.
* On FreeBSD define both LITTLE_ENDIAN and BIG_ENDIAN and then set the
BYTE_ORDER to the one we are using. On Solaris they define one or
the other but not both. For us to keep using FreeBSD header files,
we need to use endian definitions the same way we do in pure BSD
code.
use 'const' and just override it whenever we feel like it. If we use
it at all, then we need to do it properly.
Add a couple of functions that were useful in getting this code ported.
* Use the FreeBSD shell.
* On FreeBSD the tests run from the OBJDIR, so output files go there
rather than in the source tree like they do on Solaris.
* FreeBSD doesn't need a special path to the compiler.

the license review.
This change modifies the affected Makefiles to reference the sources
in their new location.
implementing some of them using existing ones.
- Allow to compile ZFS on all archs and use atomic operations surrounded
by global mutex on archs we don't have or can't have all atomic
operations needed by ZFS.
and show up with different names: first try to open provider using
remembered name and compare its ident, if equal, this is our provider,
if not equal or there is no provider with such name, find provider with
remembered ident and don't care about the name.
Before the change the command above:
# zfs set sharenfs=freefall.freebsd.org,69.147.83.54 tank/foo
was translated to:
/tank/foo -freefall.freebsd.org -69.147.83.54
instead of:
/tank/foo freefall.freebsd.org 69.147.83.54
This commit corrects this.
@118370 Correct typo.
@118371 Integrate changes from vendor.
@118491 Show backtrace on unexpected code paths.
@118494 Integrate changes from vendor.
@118504 Fix sendfile(2). I had two ways of fixing it:
1. Fixing sendfile(2) itself to use VOP_GETPAGES() instead of
hacking around with vn_rdwr(UIO_NOCOPY), which was suggested
by ups.
2. Modify ZFS behaviour to handle this special case.
Although 1 is more correct, I've choosen 2, because hack from 1
have a side-effect of beeing faster - it reads ahead MAXBSIZE
bytes instead of reading page by page. This is not easy to implement
with VOP_GETPAGES(), at least not for me in this very moment.

@118525 Reorganize the code to reduce diff.
@118526 This code path is expected. It is simply when file is opened with
O_FSYNC flag.

There are some insignificant non-style changes as well.
Not fixed: makefiles use ${LIBTHR} that doesn't exist, thus
breaking "make checkdpadd" and not tracking dependencies
properly.

ZFS file system was ported from OpenSolaris operating system. The code in under
CDDL license.
I'd like to thank all SUN developers that created this great piece of software.
