The following patches have been posted as providing at least some
partial improvement to the ext3 latency problem that has been
discussed on the 2.6.29 mongo-LKML-thread-that-would-not-die.

I plan to push this to Linus during the 2.6.29 merge window if there
are no huge objections.  It is by no means a complete solution, but it
should at least help the situation somewhat.

It is also available via git:

git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git ext3-latency-fixes

Comments?

      block_write_full_page: Use synchronous writes for WBC_SYNC_ALL writebacks
      ext3: Use WRITE_SYNC for commits which are caused by fsync()
