Some time ago i've posted comat discard support which simulate
discard by generating simple zero filled request
http://lkml.org/lkml/2010/2/11/74
Many changes was requested so i'm still working on new version (it will be
ready
soon).
But it may be useful for debugging needs with conjunction with blktrace.
