Subject: EXT4 corruption on Linus latest tree.

Built from a pull around midnight EST last night.
(Don't have the git hash, as the source is on the disk that is now inaccessable..)

This is a 3TB disk which has 1.9TB used.

I can see some files/dirs, but some top level dirs now appear empty.

About to reboot back to a safe kernel and fsck.
