Hello,

This patchset is combination of the following three patchset.

 [1] block: replace barrier with sequenced flush
 [2] block: convert to REQ_FLUSH/FUA
 [3] replace barriers with explicit flush / FUA usage

Changes from the previous postings are,

* Rebased on top of 2.6.36-rc2 (502adf5778f4151dcba3f64dd6ed322151f3712c)

Awesome, thanks!

* dm conversion is excluded for now.

...

I've audited all make_request drivers and after this patchset only
blktrace, dm, drbd and xen need more work.  I'll work on blktrace and
dm

OK, once you have the DM patch refreshed I'll jump in with further
changes (SCSI error differentiation in mpath) and more careful review of
the DM changes (both bio-based and request-based).

Thanks again!
Mike
