2fb9b26a85 * : modules/sys/kmem-slab.c : Re-implemented the slab to no
longer be based on the linux slab but to be its own complete
implementation.  The new slab behaves much more like the
Solaris slab than the Linux slab.

57d862349b Breaking the world for a little bit. If anyone is going to continue
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.

937879f11d Update SPL to use new debug infrastructure. This means:
- Replacing all BUG_ON()'s with proper ASSERT()'s
- Using ENTRY,EXIT,GOTO, and RETURN macro to instument call paths

57d1b18858 First commit of lustre style internal debug support. These
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.

728b9dd800 - Fix write-only behavior in vn-open()
- Ensure we have at least 1 write-only splat test
- Fix return codes for vn_* Solaris does not use negative return 
  codes in the kernel.  So linux errno's must be inverted.

8d0f1ee907 Add some crude debugging support. It leaves alot to be
desired, but it should allow more easy kernel debugging for now.

4e62fd4104 OK, a first reasonable attempt at a solaris module/chdev shim layer.
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.

e4f1d29f89 OK, some pretty substantial rework here. I've merged the spl-file
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!
