Almost everything I do on Linux has been with ext3.  I had a previous
diversion into VxFS and an upcoming one into XFS that may shed more
light on all this.

And, yes, the whole I/O scheduling approach in Linux was just completely
redesigned for a very recent kernel update.  So even what we think we
know is already obsolete in some respects.
