btrfs: Refactor btrfs_merge_bio_hook
This function really checks whether adding more data to the bio will straddle a stripe/chunk. So first let's give it a more appropraite name - btrfs_bio_fits_in_stripe. Secondly, the offset parameter was never used to just remove it. Thirdly, pages are submitted to either btree or data inodes so it's guaranteed that tree->ops is set so replace the check with an ASSERT. Finally, document the parameters of the function. No functional changes. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
