bump kernel version to 1.6ZD
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.
* 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
filesystem (and other things that needed to be fixed before the tests
would complete), to wit:
* Include the fs ident in the filehandle; improve stale filehandle checks.
* Change definition of blksize() to use the on-dinode size instead of
the inode's i_size, so that fsck_lfs will work properly again.
* Use b_interlock in lfs_vtruncbuf.
* Postpone dirop reclamation until after the seglock has been released,
so that lfs_truncate is not called with the segment lock held.
* Don't loop in lfs_fsync(), just write everything and wait.
* Be more careful about the interlock/uobjlock in lfs_putpages: when we
lose this lock, we have to resynchronize dirtiness of pages in each
block.
* Be sure to always write indirect blocks and update metadata in
lfs_putpages; fixes a bug that caused blocks to be accounted to the
wrong segment.
