.SH "SYNOPSIS"

.SH "DESCRIPTION"
.PP
\fBbio_endio\fR
will end I/O on the whole bio\&.
\fBbio_endio\fR
is the preferred way to end I/O on a bio\&. No one should call
\fBbi_end_io\fR
directly on a bio unless they own it and thus know that it has an end_io function\&.
.PP
\fBbio_endio\fR
can be called several times on a bio that has been chained using
\fBbio_chain\fR\&. The \->\fBbi_end_io\fR
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\&.
