Very odd indentation. Normally this would be:
if (__blkdev_issue_discard(rdev->bdev, start, size, GFP_NOIO, 0,
&discard_bio) || !discard_bio)
return;
+
+ bio_chain(discard_bio, bio);

+ submit_bio_noacct(discard_bio);

EXPORT_SYMBOL_GPL like all the other exports in md.c, please.
+extern void md_submit_discard_bio(struct mddev *mddev, struct md_rdev *rdev,
+ struct bio *bio, sector_t start, sector_t size);
no need for the extern.
Thanks for these suggestions. I'll fix them in the next version.
