Hi,

This is a *compile only RFC* which adds a generic helper to initialize
the various fields of the bio that is repeated all the places in
file-systems, block layer, and drivers.

The new helper allows callers to initialize non-optional members of bio
such as bdev, sector, op, opflags, max_bvecs and gfp_mask by
encapsulating new bio allocation with bio alloc with initialization
at one place.

The objective of this RFC is to only start a discussion, this it not 
completely tested at all.

-ck
