The series firstly fixes a few issues in handling
barriers in ordinary requests (what was overlooked
in previous patch -- see commit c2247f3745).
Then there are a few minor rework w/o functional
changes that alleviate main patches (last two ones).
And finally the series fixes handling barriers
for RELOC_A|S requests.
The main complexity comes from the following bug:
for direct_io it's not enough to send FUA to flush
all nullified cluster block. See details in
"fix barriers for PLOOP_E_RELOC_NULLIFY" patch.
