- fix writing to coda files. this is probably not the right way to do
this, but it satisfies the locking protocol:
1. Sometimes coda_open() is called with an unlocked vnode which
does not satisfy the locking protocol. Lock it for now. We
need to find out why this happens
2. VFS_VGET sometimes returns the container vnode unlocked. What
is the locking protocol for VFS_VGET? We also lock it here.
* Remove the "lwp *" argument that was added to vget(). Turns out
that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
just to appease the above.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
