"I suppose I should be glad the potential ext4 corruption that two
users have reported potentially impacting v3.6.2 and v3.6.3 has
promoted some minor increase in revenue (due to advertising hits) for
Slashdot and Phoronix, but really, people should chill out."

"That's not to say that we're not treating this seriously; I was up
until late last night trying to get a handle on it.  But folks
shouldn't be running around with their heads cut off. "

"It now looks like the reproduction involved something very esoteric
indeed, involving using umount -l and shutdowns while the file system
was still being unmounted --- and the user had nobarrier specified in
the mount options as well."

That, and the picture with the big "DON'T PANIC" letters on it.
