bio_endio — end I/O on a bio
void bio_endio ( | struct bio * bio, |
int error); |
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.
bio_endio can be called several times on a bio that has been chained
using bio_chain. The ->bi_end_io function will only be called the
last time. At this point the BLK_TA_COMPLETE tracing event will be
generated if BIO_TRACE_COMPLETION is set.
