but access control) user mounting policies: enforced MNT_NOSUID and
MNT_NODEV, no MNT_EXPORT, MNT_EXEC propagation. This can be useful for
secmodels that are interested in simply adding finer grained user mount
support.
- Add a mount subsystem listener for KAUTH_REQ_SYSTEM_MOUNT_GET.
UDF. Future users could be msdosfs, ufs, nilfs2 (when ready), cd9660 etc.
Note that its not the same as UFS's DIRHASH support; UFS would need a good
cleanup/splitout of directory operations to adopt to this new directory
hashing support since most directory operations are interweaved with the
vnops itself. This is a TODO.
Make VFS hooks dynamic while we're here and say farewell to VFS_ATTACH and
VFS_HOOKS_ATTACH linksets.
As a consequence, most of the file systems can now be loaded as new style
modules.
Quick sanity check by ad@.
- for structure fields that are conditionally present,
make those fields always present.
- for functions which are conditionally inline, make them never inline.
- remove some other functions which are conditionally defined but
don't actually do anything anymore.
- make a lock-debugging function conditional on only LOCKDEBUG.

into the "vfsops" link set.
- Use VFS_ATTACH() where vfsops are declared for individual file systems.
- In vfsinit(), traverse the "vfsops" link set, rather than vfs_list_initial[].
a vector of indices into the cfdata table to specify potential parents,
record the interface attributes that devices have and add a new "parent
spec" structure which lists the iattr, as well as optionally listing
specific parent device instances.

While here, const poison some things, as suggested by Matt Thomas.
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map). Try to deal with this:
* Group all information about the backend allocator for a pool in a
separate structure. The pool references this structure, rather than
the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
to become available, but will still fail if it cannot callocate KVA
space for the pages. If this happens, carefully drain all pools using
the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
some pages, and use that information to make draining easier and more
efficient.
* Get rid of PR_URGENT. There was only one use of it, and it could be
dealt with by the caller.

vectors; defer that to vfs_opv_init().
Change the interface to vfs_opv_init() and export it; it now takes a
pointer to an array of vnodeopv_desc *'s to initialize. Allocate
the vnode operations vectors here. Called by vfs_attach().
Implement vfs_opv_free(), which deallocates the vnode operations
vectors. Called by vfs_detach().
Change vfsinit() to build the initial vfs_list by traversing the
vfs_list_inital[] table, and vfs_attach()'ing those file systems.
Also, initialize special vnodeopv_descs (dead, fifo, spec) which
are not associated with any particular file system.
