[ Upstream commit2138e89cb0] The do_k_string() and do_c_string() functions do essentially the same thing which is they add a string and a comma onto the end of an existing string. At the end, the caller will overwrite the last comma with a newline. Later, in orangefs_kernel_debug_init(), we add a newline to the string. The change to do_k_string() is just cosmetic. I moved the "- 1" to the other side of the comparison and made it "+ 1". This has no effect on runtime, I just wanted the functions to match each other and the rest of the file. However in do_c_string(), I removed the "- 2" which allows us to print two extra characters. I noticed this issue while reviewing the code and I doubt affects anything in real life. My guess is that this was double counting the comma and the newline. The "+ 1" accounts for the newline, and the caller will delete the final comma which ensures there is enough space for the newline. Removing the "- 2" lets us print 2 more characters, but mainly it makes the code more consistent and understandable for reviewers.
