This can happen if the algos are built as modules but are not loaded. If
the selected ratectl algo is not available, try to load it (The load
module functions does nothing currently). Add a dummy ratectl algo which
always selects the first available rate. Use that one if the desired algo
is not available.

This avoids a panic when a device with an invalid name is attempted to
be registered. For example the label class gets device names from
untrusted input.

by both clients. Since the NLM uses various fields of the
nfsmount structure, those fields were extracted and put in a
separate nfs_mountcommon structure stored in sys/nfs/nfs_mountcommon.h.
This structure also has a function pointer for a function that
extracts the required information from the mount point and nfs vnode
for that particular client, for information stored differently by the
clients.

fixed the issues with file descriptor locks, but the same problems are
present for vnode lock/user map lock.
If the nfs_asyncio() cannot find the free nfsiod, schedule task to
create new nfsiod and return error. This causes fall back to the
synchronous i/o for nfs_strategy(), or does not start read at all in
the case of readahead. The caller that holds vnode and potentially
user map lock does not wait for kproc_create() to finish, preventing
the LORs.
The change effectively reverts r203072, because we never hand off the
request to newly created nfsiod thread anymore.

- Implement proper combined mode decoding for Intel controllers to properly
identify SATA and PATA channels and associate ATA channels with SATA ports.
This fixes wrong reporting and in some cases hard resets to wrong SATA ports.
- Improve SATA registers support to handle hot-plug events and potentially
interface errors. For ICH5/6300ESB chipsets these registers accessible via
PCI config space. For later ones they may be accessible via PCI BAR(5).
- For controllers not generating interrupts on hot-plug events, implement
periodic status polling. Use it to detect hot-plug on Intel and VIA
controllers. Same probably could also be used for Serverworks and SIS.

root file system (starting with devfs and a synthesized configuration) can
contain directives for mounting another file system as root. The old root
file system is re-mounted under the new root file system (with /.mount or
/mnt as the mount point) to allow access to the underlying file system.
The configuration allows for creating vnode-backed memory disks that can
subsequently be mounted as root. This allows for an efficient and low-
cost way to distribute and boot FreeBSD software images that reside on
some storage media.
When trying a mount, the kernel will wait for the device in question to
arrive. The timeout is configurable and is part of the configuration.
This allows arbitrarily complex GEOM configurations to be constructed
on the fly.
A side-effect of this change is that all root specifications, whether
compiled into the kernel or typed at the prompt can contain root mount
options.
To protect against malicious software, we demand that the file name is at

with every tick as it just won't trigger again with the (S)TICK compare
