d20e923a9c - raise spl to bio in lfs_countlocked() rather than having callers to do so. 
- buffer cache MP locks.
- assert B_CALL buffers are not on the free queue.

761c22ff58 use arc4random instead of random (mask with INT32_MAX to avoid getting 
negative numbers unexpectedly).

01e41ddfe3 don't call LFS_DEBUG_COUNTLOCKED after bread(). 
lfs_countlocked doesn't count buffers that isn't on the freelist.

92c5eba410 Split CGSIZE definition so it can be used with 64bit fpg values. 
Split cg_start so magic can be done in libsa when it is known that the
filesystem isn't UFS2.

5638922967 Stop panic if 'mknod xxx b 0 0' done on a full filesystem. 
panics in ffs_full_fsync because v_specmountpoint requires that the NULL
v_specinfo be followed.
Tidy up in the same order in all error paths so compiler can merge the
code sequences.

d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.

a06b275edc Undo part of the ktrace/lwp changes. In particular: 
* 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.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
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

ab2238cfad make is_sequential a callback in order to achieve better lfs write clustering. 
since lfs always rewrite blocks into the new segment,
current on-disk place of the block doesn't affect to write clustering.

07936511f0 The C language does not permit statements of the form

Transform these to correct C.

100c8f971f Restrict the run of cluster blocks to on-disk contiguous blocks (back out 
part of rev 1.115), to avoid writing over holes.  This is the lesser of two
