That's right. It can be aware of that. I just want to make the code easy to read and limit the textwidth to 80 character. If the message takes two lines as bellow, printk("xxx " ^ space character. "yyy"); The checkpatch.pl could also be aware of that if the first line is not end with space character, but it couldn't be aware of that if run with "checkpatch.pl -f xxxx.patch". >> Fixes: 563e0bb0dc74("net: tracepoint: replace tcp_set_state tracepoint >> with >> inet_sock_set_state tracepoint") >> Signed-off-by: Yafang Shao <laoar.shao@gmail.com> > > [...] > > MBR, Sergei

Yes, that too.

It is aware --- I'm just not sure it recognizes TP_printk() -- like it does recognize printk() fo that purpose. > I just want to make the code easy to read and limit the textwidth to > 80 character. Contrariwise, that's what you shouldn't do. Would simplify searching for the messages in the kernel source. > If the message takes two lines as bellow, > printk("xxx " > ^ space character. > "yyy"); > The checkpatch.pl could also be aware of that if the first line is > not end with space character, but it couldn't be aware of that if run > with "checkpatch.pl -f xxxx.patch". Option -f tells checkpatch.pl that it should check a source file, not a patch. I don't know why you use that with the patches... >>> Fixes: 563e0bb0dc74("net: tracepoint: replace tcp_set_state tracepoint >>> with >>> inet_sock_set_state tracepoint") >>> Signed-off-by: Yafang Shao <laoar.shao@gmail.com> [...] MBR, Sergei

There's a space character missed in the printk messages. This error should be prevented with checkscript.pl, but it couldn't caught by running with "checkscript.pl -f xxxx.patch", that's what I had run before. What a carelessness.
