Subject: Ordered data mode vs. writeback mode

Noticed that the newest set of patches in ext4-patch-queue has ordered data
mode as the default mode again. Tune2fs is now able to switch modes again.

What is the preferred mode for a home desktop system with ext4? Is
writeback still the fastest, but ordered data has more data integrity?  And
does delalloc only work when writeback is enabled? And does the commit=XX
seconds still only work with writeback mode, ala ext3, or is it a valid
option with ordered data mode?

Trying to get an idea of the plethora of new options available with ext4.

Keep up the good work!
