An excerpt from the Committer's Guide, Rule 5:

"...unless the -STABLE fix is critical, time sensitive or so obvious as to make
further testing unnecessary (spelling fixes to manpages, obvious bug/typo
fixes, etc.)"

If you had looked at a) the patch, and b) the thread on -hackers, you would
have seen that this is an obvious bug/typo, and for people who use
phy_backed_shm a critical fix since the functionality was badly broken.  This
option is not on by default and is most likely not being used by anyone running
-current right now as it is a very special case.  I'll also note the very end
of rule 5:

"In other words, apply common sense."
