9660 block size are long gone and we can't use cluster_read on modern
machines, improve the dumb read-ahead.
Doesn't change much on macppc and sparc64, but gives a nice speed boost on
i386 (noone knows why). espie can watch his DVDs again.
espie@ ok (noone else complained)

machines or some configurations or in some phase of the moon (we actually
don't know when or why) files disappeared. Since we've not been able to
track down the problem in two weeks intense debugging and we need -current
to be stable, back out everything to a state it had before UBC.
We apologise for the inconvenience.

is only in the vnodeops in VREG and VDIR vnodes, we can remove tons of
code here.
|
|
- get rid of VOP_BALLOCN and VOP_SIZE
- move the generic getpages and putpages into miscfs/genfs
- create a genfs_node which must be added to the top of the private portion
of each vnode for filsystems that want to use genfs_{get,put}pages
- rename genfs_mmap to vop_generic_mmap

the filesystem if we're allowed to mmap the file.

code is written mostly by Chuck Silvers <chuq@chuq.com>/<chs@netbsd.org>.
Tested for the past few weeks by many developers, should be in a pretty stable
state, but will require optimizations and additional cleanups.

file system inode instead

returned is in 512-byte sectors, so if you're going to use it for
things like DVD, you need to divide the result by 4 (for 2048-byte
sectors). OK deraadt@

to be vop_generic_revoke, vop_generic_bwrite, vop_generic_islocked,
vop_generic_lock and vop_generic_unlock.
Create vop_generic_abortop and propogate change to all file systems.
Fix PR/371.
Get rid of locking in NULLFS (should be mostly unnecessary now except for
forced unmounts).

"goto start" after sleeping for locked iso_node in cd9660_lock, like
in ufs_lock.
NBPG may not be computable by the preprocessor. Make "do clustered io"
a run-time decision. Note: the compiler can optimize it away.
