BIO_CHAIN(9)                              The Linux VFS                              BIO_CHAIN(9)



NAME
       bio_chain - chain bio completions

SYNOPSIS
       void bio_chain(struct bio * bio, struct bio * parent);

ARGUMENTS
       bio
           the target bio

       parent
           the bio's parent bio

DESCRIPTION
       The caller won't have a bi_end_io called when bio completes - instead, parent's bi_end_io
       won't be called until both parent and bio have completed; the chained bio will also be
       freed when it completes.

       The caller must not set bi_private or bi_end_io in bio.
