file via NFS. Specifically, to satisfy close-to-open-consistency, the NFS
client always performs at least one RPC on a file during an open(2) to see
if the file has changed. Normally this RPC is an ACCESS or GETATTR RPC
that is forced by flushing a file's attribute cache during nfs_open() and
then requesting new attributes. However, if the file is noticed to be
stale during nfs_open(), the only recourse is to fail the open(2) call
with ESTALE. On the other hand, if the ACCESS or GETATTR RPC is sent
during nfs_lookup(), then the NFS client can fall back to a LOOKUP RPC to
obtain the new file handle in the case that a file has been replaced.
This change causes the NFS client to flush the attribute cache during
nfs_lookup() when validating a name cache hit if the attributes fetched
during nfs_lookup() can be reused in nfs_open(). This allows the client
to open a replaced file via the new file handle the first time that it
notices a replaced file rather than failing with ESTALE in some cases.

There's a parsing error for fields where addresses are not separated by
space. This is often produced by MS Outlook, eg.:
Cc: <foo@bar.com>,"Mr Foo" <foo@baz.com>
The following line now splits into the right tokens:
Cc: f@b.com,z@y.de, <a@a.de>,<c@c.de>, "foo" <foo>,"bar" <bar>

acquisitions from vm_map_pmap_enter() and mincore(), respectively. In
mincore(), this allows some additional cases to complete without ever
acquiring the page queues lock.

On powerpc/aim, push down the page queues lock acquisition from
moea*_is_modified() and moea*_is_referenced() into moea*_query_bit().
Again, this will allow some additional cases to complete without ever
acquiring the page queues lock.
Reorder a few statements in vm_page_dontneed() so that a race can't lead

comment.
Correct a spelling error in vm_page_dontneed().
Assert that the object is locked in vm_page_clear_dirty(), and restrict the
page queues lock assertion to just those cases in which the page is
currently writeable.
Add object locking to vnode_pager_generic_putpages(). This was the one
and only place where vm_page_clear_dirty() was being called without the
object being locked.
Eliminate an unnecessary vm_page_lock() around vnode_pager_setsize()'s call
to vm_page_clear_dirty().
Change vnode_pager_generic_putpages() to the modern-style of function
definition. Also, change the name of one of the parameters to follow
virtual memory system naming conventions.

trigger the problem, doesn't do so consistently due to the nature of the

The driver is stub. It just creates device entry and feeds
reassembled packets from hardware into it.
If in future we would port wsmouse(4) from NetBSD, or make
sysmouse(4) to support absolute motion events, then the driver
can be extended to act as system mouse. Meanwhile, it just
presents a /dev/uep0, that can be utilized by X driver, that
I am going to commit to ports tree soon.
The name for the driver is chosen to be the same as in NetBSD,
however, due to different USB stacks this driver isn't a port.
