working on this branch for the next few days I suggested you work
off of the 0.3.1 tag. The following changes are fairly extensive
and are designed to make the SPL compatible with all kernels in
the range of 2.6.18-2.6.25. There were 13 relevant API changes
between these releases and I have added the needed autoconf tests
to check for them. However, this has not all been tested extensively.
I'll sort of the breakage on Fedora Core 9 and RHEL5 this week.

other primitive implementations. Additionally ensure that GFP_ATOMIC
is use for allocations when in interrupt context.

not to support a few flags (we assert if they are used), and I
did not add the libkstat interface and instead exported everything
to proc for easy access.

crashes but it's not clear to me yet if these are a problem with
the mutex implementation or ZFSs usage of it.
Minor taskq fixes to add new tasks to the end of the pending list.
Minor enhansements to the debug infrastructure.

changes bring over everything lustre had for debugging with
two exceptions. I dropped by the debug daemon and upcalls
just because it made things a little easier. They can be
readded easily enough if we feel they are needed.
Everything compiles and seems to work on first inspection
but I suspect there are a handful of issues still lingering
which I'll be sorting out right away. I just wanted to get
all these changes commited and safe. I'm getting a little
paranoid about losing them.

what I would call effecient but it does have the advantage
of being correct which is all I need right now. I added
a regression test as well.

This should handle the absolute minimum I need for ZFS. It will
register the chdev with the right callbacks. Then the generic
registered linux callback will find the right registered solaris
callback for the function and munge the args just right before
passing it on. Should work, but untested (just compiled), so I
expect bugs.

stuff which only inclused the getf()/releasef() in to the vnode area
where it will only really be used. These calls allow a user to
grab an open file struct given only the known open fd for a particular
user context. ZFS makes use of these, but they're a bit tricky to
test from within the kernel since you already need the file open
and know the fd. So we basically spook the system calls to setup
the environment we need for the splat test case and verify given
just the know fd we can get the file, create the needed vnode, and
then use the vnode interface as usual to read and write from it.
While I was hacking away I also noticed a NULL termination issue
in the second kobj test case so I fixed that too. In fact, I fixed
a few other things as well but all for the best!

Update check.sh script to take V=1 env var so you can run it verbosely as
follows if your chasing something: sudo make check V=1
Add new kobj api and needed regression tests to allow reading of files from
within the kernel. Normally thats not something I support but the spa layer
needs the support for its config file.
Add some more missing stub headers

We've dropped all the linux- prefixes on the file in favor of spl-
which makes more sense. And we've cleaned up some of the includes
so everybody should be including their own dependencies properly.
All a module which wants to use the spl support needs to do in
include spl.h and ensure it has access to Module.symvers.

the directories at the top level but that proved troublesome. The
kernel buildsystem and autoconf were conflicting too much. To
resolve the issue I moved the kernel bits in to a modules directory
which can then only use the kernel build system. We just pass
along the likely make targets to the kernel build system.
