In the Linux kernel, the following vulnerability has been resolved:
md/raid1,raid10: fix bio accounting for split md cloned bios
Use md_cloned_bio() to control bio accounting instead of relying
on r1bio_existed in raid1 or the io_accounting flag in raid10.
The previous logic does not reliably reflect whether a bio is an
md cloned bio. When a failed bio is split and resubmitted via
bio_submit_split_bioset() on the error path, this can lead to either
double accounting for md cloned bios, or missing accounting for bios
returned from bio_submit_split_bioset()
Fix this by using md_cloned_bio() to detect md cloned bios and
skip accounting accordingly.
