61d5d4362b fix a bug of lfs. 
genfs_getpages() can read in more blocks than it should due to faked filesize
of lfs_gop_size().  it's a security problem and it makes gcc3 "internal error"

to fix this,
- in genfs_getpages(), always calculate diskeof and memeof separately
  so that filesystems (in this case, lfs) can use different strategies
  for them.
- introduce GOP_SIZE_MEM flag and use it to request in-core filesize.
  (it was an intention of GOP_SIZE_READ,
  but after the above change _READ is not a straightforward name)

after this, no one uses GOP_SIZE_{READ,WRITE} anymore but leave them for now.

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.

75208caf18 Adapt for struct proc* -> struct lwp* changes. 2003-06-28 22:53:35 +00:00
darrenr
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.
