  Thanks, but please include Ted Ts'o <tytso@....edu> in JBD2 patches.
Thanks.

Ted, I've realized that MAINTAINERS has only entry like:
JOURNALLING LAYER FOR BLOCK DEVICES (JBD)
M:      Andrew Morton <akpm@...ux-foundation.org>
M:      Jan Kara <jack@...e.cz>
L:      linux-ext4@...r.kernel.org
S:      Maintained
F:      fs/jbd*/
F:      include/linux/ext*jbd*.h
F:      include/linux/jbd*.h

I guess you should add a separate entry for JBD2 so that people will find
you ;).
