This means that we may miss panics on a class of mutex programming bugs,
but only if running with a Chernobyl setting of debug-flags.

long doubles at the moment (printf truncates them to doubles).
However, long doubles to appear to work to the ranges listed in this
commit on both -stable (4.5) and -current. There may be some slight
rounding issues with long doubles, but that's an orthogonal issue to
these constants.
I've had this in my local tree for 3 months, and in my company's local
tree for 15 months with no ill effects.

code is directly copied from migrate.c. The intend is to express
migrate in terms of create and add. The functionality to add
partitions is not yet there.
closed through _fetch_close() which is the only one who knows the connection
REALLY was closed (since ref -> 0). However, FTP keeps its own local
cached_connection and checks if it is valid by comparing it to NULL. This
is bogus since it may have been freed elsewhere by _fetch_close().
This change checks if we are closing the cached_connection and the ref is 1
(soon to be 0). If so, set cached_connection to NULL so we don't
accidentally reuse it. The REAL fix should be to move connection caching
to the common.c level (_fetch_* functions) and NULL the cache(s) in
_fetch_close(). Then all layers could benefit from caching.
check for and/or report I/O errors. The result is that a VFS_SYNC
or VOP_FSYNC called with MNT_WAIT could loop infinitely on ufs in
the presence of a hard error writing a disk sector or in a filesystem
full condition. This patch ensures that I/O errors will always be
checked and returned. This patch also ensures that every call to
VFS_SYNC or VOP_FSYNC with MNT_WAIT set checks for and takes
appropriate action when an error is returned.

so that KSEs with no mailbox in a KSE program are not a cause
of page faults (this can legitmatly happen).

because the variable is often unset, but this is not always the
case e.g. when you call "MAKEDEV sio2 usb ..."
This affects -stable as well.
