This looks like a biggish change for after -rc6, and the commit
message doesn't tell me what dire things will happen if the patch
doesn't go in, or what systems see this breakage, or whether this is a
regression since 2.6.26 (I assume it isn't).  It doesn't even tell me
why not being thread-safe is a problem on a UP machine.

So... why does this fix need to go in at this stage?

Paul.
