bio_endio — end I/O on a bio
void bio_endio (
struct bio * bio, unsigned int bytes_done, int error)
;
bio_endio
will end I/O on bytes_done
number of bytes. This may be
just a partial part of the bio, or it may be the whole bio. bio_endio
is the preferred way to end I/O on a bio, it takes care of decrementing
bi_size and 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. Noone should call bi_end_io
directly on
a bio unless they own it and thus know that it has an end_io function.
