We cover all log-levels by pr_... macros except
KERN_CONT one. Add it for convenience.
Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org>

I think start printing with some pr_... macro
and continue with printk(KERN_CONT ...) look
not that clear -- better to continue with
same pr_... slogan. Thoughts? I hope I didn't
miss anything.

Makes sense.

Don't you want to omit the pr_fmt() from the KERN_CONT case?

indeed, good catch. It should be:
#define pr_cont(fmt, ...) \
printk(KERN_CONT ##__VA_ARGS__)
To not introduce stale subsystem tags in the printout. Perhaps
it should even be:
#define __pr_cont(fmt, ...) \
printk(KERN_CONT ##__VA_ARGS__)
To make it stand out more clearly that this is special.

yeah ...
Btw., why do those macros use ##__VA_ARGS__ ? Why not a
straightforward:
#define __pr_cont(args...) \
printk(KERN_CONT args)
?

Don't know if anyone cares, but __VA_ARGS__ is C99 whereas args... is a
gcc extension, AFAIK.

I think in a sake of consistency better would be using __VA_ARGS__ here
too (since all prevous pr_...'s use it).

Subject: [PATCH] introduce pr_cont macro v2
We cover all log-levels by pr_... macros except
KERN_CONT one. Add it for convenience.
Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org>
---
Using 'fmt' here make this macro look similar
to others (same missioned) macros. Which is
good :)
