Personally, I find them rather ugly myself. The only user of them I see in the kernel/ directory appears to be for RCU. But Paul's on the C/C++ committee, so perhaps he favors them. The net/ directory doesn't have any, except perhaps to comment out code (which I sometimes use it for that too). The block/, arch/x86/ directories don't have them either. I wouldn't go and change checkpatch, but I still rather avoid them, especially for multi line comments. /* * When it comes to multi line comments I prefer using something * that denotes a start and an end to the comment, as it makes it * look like a nice clip of information. */ Instead of: // When it comes to multi line comments I prefer using something // that denotes a start and an end to the comment, as it makes it // look like a nice clip of information. Which just looks like noise. But hey, maybe that's just me because I find "*" as a sign of information and '//' something to ignore. ;-) -- Steve
