cb07628d9e nfscl: Delete unneeded redundant MODULE_DEPEND() calls
There are two module declarations in the nfscl.ko module for "nfscl"
and "nfs".  Both of these declarations had MODULE_DEPEND() calls.
This patch deletes the MODULE_DEPEND() calls for "nfs" to avoid
confusion with respect to what modules this module is dependent upon.

The patch also adds comments explaining why there are two module
declarations within the module.

caller-supplied buffer isn't big enough.  In this case the error must be

630caa95d4 rtld: preserve the 'seen' state of the dlerror message in errmsg_save()
rtld preserves its current error message around calls to user init/fini
lists, to not override original error with potential secondary errors
caused by user code recursing into rtld.  After 4d9128da54,
the preservation of the string itself is not enough, the 'seen'
indicator must be preserved as well.  Otherwise, since new code does not
clear string (it cannot), call to _rtld_error() from errmsg_restore()
revived whatever message was consumed last.

Change errmsg_save() to return structure recording both 'seen' indicator
and the message, if any.

9867224bab tcp:Host cache and rack ending up with incorrect values.
The hostcache up to now as been updated in the discard callback
but without checking if we are all done (the race where there are
more than one calls and the counter has not yet reached zero). This
means that when the race occurs, we end up calling the hc_upate
more than once. Also alternate stacks can keep there srtt/rttvar
in different formats (example rack keeps its values in microseconds).
Since we call the hc_update *before* the stack fini() then the
values will be in the wrong format.

Rack on the other hand, needs to convert items pulled from the
hostcache into its internal format else it may end up with
very much incorrect values from the hostcache. In the process
lets commonize the update mechanism for srtt/rttvar since we
now have more than one place that needs to call it.

2ef5d803e3 in6_mcast: Return EADDRINUSE when we've already joined the group
Distinguish between truly invalid requests and those that fail because
we've already joined the group. Both cases fail, but differentiating
them allows userspace to make more informed decisions about what the
error means.

For example. radvd tries to join the all-routers group on every SIGHUP.
This fails, because it's already joined it, but this failure should be
ignored (rather than treated as a sign that the interface's multicast is
broken).

This puts us in line with OpenBSD, NetBSD and Linux.

aad59c79f5 Fix panic when trying to delete non-existent gateway in multipath route.
IF non-existend gateway was specified, the code responsible for calculating
 an updated nexthop group, returned the same already-used nexthop group.
After the route table update, the operation result contained the same
 old & new nexthop groups. Thus, the code responsible for decomposing
 the notification to the list of simple nexthop-level notifications,
 was not able to find any differences. As a result, it hasn't updated any
  of the "simple" notification fields, resulting in empty rtentry pointer.
This empty pointer was the direct reason of a panic.

Fix the problem by returning ESRCH when the new nexthop group is the same
 as the old one after applying gateway filter.

a1fadf7de2 divert: Fix mbuf ownership confusion in div_output()
div_output_outbound() and div_output_inbound() relied on the caller to
free the mbuf if an error occurred.  However, this is contrary to the
semantics of their callees, ip_output(), ip6_output() and
netisr_queue_src(), which always consume the mbuf.  So, if one of these
functions returned an error, that would get propagated up to
div_output(), resulting in a double free.

Fix the problem by making div_output_outbound() and div_output_inbound()
responsible for freeing the mbuf in all cases.

4b8365d752 Add OBJT_SWAP_TMPFS pager
This is OBJT_SWAP pager, specialized for tmpfs.  Right now, both swap pager
and generic vm code have to explicitly handle swap objects which are tmpfs
vnode v_object, in the special ways.  Replace (almost) all such places with
proper methods.

Since VM still needs a notion of the 'swap object', regardless of its
use, add yet another type-classification flag OBJ_SWAP. Set it in
vm_object_allocate() where other type-class flags are set.

This change almost completely eliminates the knowledge of tmpfs from VM,
and opens a way to make OBJT_SWAP_TMPFS loadable from tmpfs.ko.
