SUBMIT_BIO(9)							   Block Devices						     SUBMIT_BIO(9)

NAME
       submit_bio - submit a bio to the block device layer for I/O

SYNOPSIS
       void submit_bio(int rw, struct bio * bio);

ARGUMENTS
       rw
	   whether to READ or WRITE, or maybe to READA (read ahead)

       bio
	   The struct bio which describes the I/O

DESCRIPTION
       submit_bio is very similar in purpose to generic_make_request, and uses that function to do most of the work. Both are fairly rough
       interfaces; bio must be presetup and ready for I/O.
