[dm-devel] [PATCH] use WRITE_FLUSH instead of REQ_FLUSH

[Mikulas Patocka]

Hi Alasdair

Please push this patch to 3.8 kernel. (I already sent it before, but it 
was forgotten somehow).

dm-bufio: use WRITE_FLUSH instead of REQ_FLUSH

Use WRITE_FLUSH instead of REQ_FLUSH to make it consistent with the rest
of the kernel. There is no functional change - the kernel accepts either
WRITE_FLUSH or REQ_FLUSH.
