Joe,
Sorry for the late comment.
spin_lock(&m->path_lock);
path = __find_path(m, bio->bi_bdev);
__fail_path(path);
+ r = __remap_io(m, bio);
spin_unlock(&m->path_lock);
- r = __resubmit_io(m, bio);
+ if (!r) {
+ /* queue for the daemon to resubmit */
+ spin_lock_irqsave(&m->failed_lock, flags);
+ bio->bi_next = m->failed_ios;
+ m->failed_ios = bio;
+ spin_unlock_irqrestore(&m->failed_lock, flags);

I think it might be better if the __remap_io call was in
dispatch_failed_ios before generic_make_request is called.
dispatch_failed_ios would need to be tweaked to handle __remap_io
failing, but similar modifications are needed for devices that need to
send a command to activate a path before it can be used.
