I.e the correct thing here should be to have only fs_devices->latest_bdev on a new line, even if the string goes above the char limit of 80. In any case the \ is not needed due to gcc's support for string literal concatenation: pr_err("BTRFS error (device %pg): " "unsupported checksum algorithm", fs_devices->latest_bdev) should work equally well. But as I said I don't think this is even needed. Let's wait and see what David says.The strings should not be split, because we want to be able to grep the sources for the error messages. If the string does not fit 80 chars per line, then it can be moved to the next line and un-indented to the left. Plenty of examples.
I understand reason behind string should not be split, but I thought here will be an exception, as if you want to search for the string you will still use "unsupported checksum algorithm" which is still in one line. About the grep not able to find the string which are split, I look at it as fixing the wrong end of the problem. That is Grep end problem being fixes at the c code end. Anyway as its kind of linux general guidlines, I shall fix my patch.
