Hi Jens,

this series removes the READ_* and WRITE_* defintions from fs.h and makes
all bio submitters use the REQ_* flags directly.  To make that easier
we also change the meaning of some of the flags slightly, so that the
callers don't have to set half a dozen flags for normal operations.

After that the READ and WRITE defintions are decouple from REQ_OP_READ
and REQ_OP_WRITE and moved to kernel.h, and last but not least we can
now stop including blk_types.h from fs.h and avoid the CONFIG_BLOCK
ifdefs in it.

Looks sane to me, and passes basic testing as well. Applied for 4.10.
