Sorry, I was going to send you a note about it just now, but I hadn't
gotten around to hitting the send button yet.

I had updated the for_linus branch to fix a regression that had shown
up in -rc2 due to an quota/ext4 journal fix that turned out to cause a
BUG_ON to trip in fs/ext4/inode.c:1063 (kernel bug #14936, on Rafael's
regression list) when mounting unconverted ext3 file systems using the
ext4 file system driver.  It was hitting a lot of users who had been
playing with ext4, so I wanted to get the fix to you as soon as
possible.

Here's the updated summary:
