36d60f3bb7 Remove mntvnode_mtx and replace it with per-mountpoint mutex.
Introduce two new macros MNT_ILOCK(mp)/MNT_IUNLOCK(mp) to
operate on this mutex transparently.

Eventually new mutex will be protecting more fields in
struct mount, not only vnode list.

871953665f Include <sys/mutex.h>. Don't depend on namespace pollution in <sys/vnode.h>.
Fixed a nearby style bug.  The include of vcoda.h used angle brackets and
was not used.

c95a875344 - Make proper use of the mntvnode_mtx. We do not need the loop label
because we do not drop the mntvnode_mtx.  If this code had ever executed
   and hit the loop condition it would have spun forever.

ffc45a6f38 Add support for the Coda 6.x venus<->kernel interface. This extends
FIDs to be 128-bits wide and adds support for realms.

Add a new CODA_COMPAT_5 option, which requests support for the old
Coda 5.x interface instead of the new one.

Create a new coda5.ko module that supports the 5.x interface, and make
the existing coda.ko module use the new 6.x interface. These modules
cannot both be loaded at the same time.

Obtained from:	Jan Harkes & the coda-6.0.2 distribution,
		NetBSD (drochner) (CODA_COMPAT_5 option).

02517b6731 - Replace v_flag with v_iflag and v_vflag
- v_vflag is protected by the vnode lock and is used when synchronization
   with VOP calls is needed.
 - v_iflag is protected by interlock and is used for dealing with vnode
   management issues.  These flags include X/O LOCK, FREE, DOOMED, etc.
 - All accesses to v_iflag and v_vflag have either been locked or marked with
   mp_fixme's.
 - Many ASSERT_VOP_LOCKED calls have been added where the locking was not
   clear.
 - Many functions in vfs_subr.c were restructured to provide for stronger
   locking.

2e75617aaf Don't put a line break in string literals. GCC 3.1 complains and GCC
3.2 drops the ball.

235dffbc18 Backed out vestiges of the quick fixes for the transient breakage of
<sys/mount.h> in rev.1.106 of the latter (don't include <sys/socket.h>
just to work around bugs in <sys/mount.h>).

bcca5847d5 Undo part of the tangle of having sys/lock.h and sys/mutex.h included in
other "system" header files.

Also help the deprecation of lockmgr.h by making it a sub-include of
sys/lock.h and removing sys/lockmgr.h form kernel .c files.

Sort sys/*.h includes where possible in affected files.
