XFS got some fixes recently, of which the main one was to fix the regressions that gcc 4.x introduced by inlining single use functions that we'd split out of the common code to reduce stack usage. So in reality, there hasn't been a great deal of change in the status quo here. In fact, things have probably got worse because the generic writeback code is slowly increasing it's stack usage....
