Yes, I have jbd-fix-return-value-of-journal_start_commit.patch and
revert-ext3-wait-on-all-pending-commits-in-ext3_sync_fs.patch queued
for 2.6.29.

The secret algorithm for determining this is to peek in the series file
(http://userweb.kernel.org/~akpm/mmotm/series) and see where I positioned the
patch:

#
-> # more 2.6.29 queue:
#
# me:
#
