BIO_ENDIO(9)							   The Linux VFS						      BIO_ENDIO(9)

NAME
       bio_endio - end I/O on a bio

SYNOPSIS
       void bio_endio(struct bio * bio, int error);

ARGUMENTS
       bio
	   bio

       error
	   error, if any

DESCRIPTION
       bio_endio will end I/O on the whole bio.  bio_endio is the preferred way to end I/O on a bio, it takes care of clearing BIO_UPTODATE on
       error.  error is 0 on success, and and one of the established -Exxxx (-EIO, for instance) error values in case something went wrong. No one
       should call bi_end_io directly on a bio unless they own it and thus know that it has an end_io function.
