1761 * bio_endio - end I/O on a bio
1762 * @bio: bio
1763 *
1764 * Description:
1765 * bio_endio() will end I/O on the whole bio. bio_endio() is the
preferred
1766 * way to end I/O on a bio. No one should call bi_end_io() directly
on a
1767 * bio unless they own it and thus know that it has an end_io
function.
1768 *
1769 * bio_endio() can be called several times on a bio that has been
chained
1770 * using bio_chain(). The ->bi_end_io() function will only be called
the
1771 * last time. At this point the BLK_TA_COMPLETE tracing event will be
1772 * generated if BIO_TRACE_COMPLETION is set.
