I fear that the forest is getting lost for the trees here. :)
Under most (90% or more) circumstances "stuff," be that kernel modules
or userland binaries, that is on a -stable system will still work in
its current form after you do an upgrade. In the event of an actual
ABI breakage you would be informed of when and where to tune for
additional .... wait, wrong PSA. If this had actually been an ABI
breakage then any userland binaries that depend on the thing that
changed would have to be recompiled after the update in order to
continue working. Since this is actually a KERNEL interface that's
changing, any kernel modules that use this interface (which is quite a
lot) will have to be recompiled _as part of the update_ for them to work.
If you are not using any 3rd party kernel modules (commercial, ports
tree, etc.) then you have nothing to worry about. Your FreeBSD kernel
modules will be updated along with the kernel, and everyone is happy.
If you are using a 3rd party module from ports that deals with file
systems (and yes, FUSE is an obvious example here) then you'll need to
pkg_delete it, do the update, then recompile. Q.E.D.
If you happen to be using a commercial (i.e., you don't have the
source) kernel module that deals with file systems now is the time to
contact your vendor and let them know about this issue. However, as
Ken rightly pointed out this change will actually impact a very small
percentage of FreeBSD users, and the majority of that impact will be
recompiling a port as described above.
I should also point out that FreeBSD developers deal with this issue
all the time on -current since things there are allowed to change, and
sometimes do change quite often. Therefore it's easy for us to forget
to list important details about a change like this since it's second
nature to us.
