Possibly, but the btrfs code uses bio_clone() and there fs_bio_set may be correct (will have to look at what it's doing, if it's cloning a bio that was allocated out of fs_bio_set that would be bad..) I would also prefer to simply drop bio_clone() so that bio_clone_bioset() matches bio_alloc_bioset(), but regardless that'll have to be a different patch (and I don't think I've had to update any of the bio_clone() callers in this patch series anyways). -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
