"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." http://thread.gmane.org/gmane.linux.kernel/1379725/focus=3D34994 http://thread.gmane.org/gmane.linux.kernel/1379725/focus=3D35003 That, and the picture with the big "DON'T PANIC" letters on it.
