8c21bc6224 Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD. 
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

Welcome to 2.0F.

e6416b1b3c rather than just try to get a mapping from a device as only PROT_EXEC, work

8368dac6a2 fix a amap_wirerange deadlock problem by re-introducing 
PG_RELEASED for anon pages.  PR/23171 from Christian Limpach.
for details, see discussion filed in the PR database.

uvm_anon_release: a new function to free anon-owned PG_RELEASED page.
uvm_anfree: we can't wait for the page here because the caller might hold
	amap lock.  instead, just mark the page as PG_RELEASED.
	who unbusy the page should check the PG_RELEASED.
uvm_aio_aiodone: uvm_anon_release() instead of uvm_page_unbusy()
	if appropriate.
uvmfault_anonget: check PG_RELEASED.
