miscfs/deadfs/deadfs.h: New home for deadfs-related externs.

XXX regen sys/kern/vnode_if.c and the others

Make dead vfs ops "vfs_statvfs" and "vfs_vptofh" return EOPNOTSUPP.
Both operations may originate from (possible dead) vnodes.

Reported-by: syzbot+eceb203d44457742be3b@syzkaller.appspotmail.com

Remove now unused VV_LOCKSWORK, all file systems support locking.

Remove unused predicates vn_locked() and vn_anylocked().

Welcome to 9.99.95

Switch spec_vnodeop vector to real vnode locking, VV_LOCKSWORK now.

Add "void *extra" argument to vcache_new() so a file system may
pass more information about the file to create.

Change forced unmount to revert open device vnodes to anonymous devices.

No need to cache anonymous device vnodes, they will never be looked up.

Unfortunately MFS uses v_data of its anonymous device vnode so
it cannot be used as vcache key.  Use v_interlock as key ...

Redo previous again, v_specnode is invariant but not unique.

Set "vp->v_data = vp" and use v_data as key.

Use the address of vp->v_specnode as vcache key.  It is invariant
over the lifetime of the vnode.

The previous worked by luck, it took the first sizeof(void *) bytes
of struct vnode as key.

Resolves CID 1308957: wrong sizeof()

Add a vfs_newvnode() method to deadfs and use it to create
anonymous device vnodes with bdevvp() and cdevvp().

Implement spec_inactive() and spec_reclaim() to handle these nodes.

Use VFS_PROTOS() for deadfs.  Rename dead_mount to dead_rootmount.

Rebase to HEAD as of a few days ago.

Change all vfsops to use C99 designated initializers.

No functional changes intended.

Currently dead vnodes still reside on the vnodelist of the file system
they have been removed from.

Create a "dead mount" that takes dead vnodes until they get freed.

Discussed on tech-kern.
