29796304f8 Do not call VOP_BMAP() on our own vnodes.
It is particularly silly when all it does is a minor piece of math.

a0595d0249 Add a flags parameter to VFS_VGET to pass through the desired
locking flags when acquiring a vnode. The immediate purpose is
to allow polling lock requests (LK_NOWAIT) needed by soft updates
to avoid deadlock when enlisting other processes to help with
the background cleanup. For the future it will allow the use of
shared locks for read access to vnodes. This change touches a
lot of files as it affects most filesystems within the system.
It has been well tested on FFS, loopback, and CD-ROM filesystems.
only lightly on the others, so if you find a problem there, please
let me (mckusick@mckusick.com) know.

aa454a4b53 Fix a bug in CD9660 when vmiodirenable is turned on. CD9660 was assuming
that a buffer's b_blkno would be valid.  This is true when vmiodirenable
is turned off because the B_MALLOC'd buffer's data is invalidated when
the buffer is destroyed.  But when vmiodirenable is turned on a buffer
can be reconstituted from its VMIO backing store.  The reconstituted buffer
will have no knowledge of the physical block translation and the result is
serious directory corruption of the CDROM.

The solution is to fix cd9660_blkatoff() to always BMAP the buffer if
b_lblkno == b_blkno.

Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

9626b608de Separate the struct bio related stuff out of <sys/buf.h> into
<sys/bio.h>.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.

Still a few bogus uses of struct buf to track down.

cec0f20ce7 VFS mega cleanup commit (x/N)
1.  Add new file "sys/kern/vfs_default.c" where default actions for
    VOPs go. Implement proper defaults for ABORTOP, BWRITE, LEASE,
    POLL, REVOKE and STRATEGY.  Various stuff spread over the entire
    tree belongs here.

2.  Change VOP_BLKATOFF to a normal function in cd9660.

3.  Kill VOP_BLKATOFF, VOP_TRUNCATE, VOP_VFREE, VOP_VALLOC.  These
    are private interface functions between UFS and the underlying
    storage manager layer (FFS/LFS/MFS/EXT2FS).  The functions now
    live in struct ufsmount instead.

4.  Remove a kludge of VOP_ functions in all filesystems, that did
    nothing but obscure the simplicity and break the expandability.
    If a filesystem doesn't implement VOP_FOO, it shouldn't have an
    entry for it in its vnops table.  The system will try to DTRT
    if it is not implemented.  There are still some cruft left, but
    the bulk of it is done.

5.  Fix another VCALL in vfs_cache.c (thanks Bruce!)

0fa2443f0e Uncut&paste cache_lookup().
This unifies several times in theory indentical 50 lines of code.

The filesystems have a new method: vop_cachedlookup, which is the
meat of the lookup, and use vfs_cache_lookup() for their vop_lookup
method.  vfs_cache_lookup() will check the namecache and pass on
to the vop_cachedlookup method in case of a miss.

It's still the task of the individual filesystems to populate the
namecache with cache_enter().

Filesystems that do not use the namecache will just provide the
vop_lookup method as usual.

2a31d924ab Use the common nchstats struct instead of a private one for ncs_2passes
and ncs_pass2.  The public one is already used for other cd9660 statistics
and the private one was effectively invisible.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

The fix for this in Lite-2 is more complete, but these quick hacks of mine

later time. Should completely fix PR810.

d68a41903e Moved the filesystem read-only check out of the syscalls and into the
filesystem layer, as was done in lite-2. Merged in some other cosmetic
changes while I was at it. Rewrote most of msdosfs_access() to be more
like ufs_access() and to include the FS read-only check.

988fa8efe3 Roll in my changes to make the cd9660 code understand the older
(original "High Sierra") CD format.  I've already implemented this for
1.1.5.1 (and posted to -hackers), but didn't get any response to it.
Perhaps i'm the only one who has such an old CD lying around...

Everything is done empirically, but i had three of them around (from
different vendors), so there's a high probability that i've got it
right. :)
