Hi Kent.
I generally prefer pr_debug but maybe here's
a couple of things you don't already know.
> +#define pr_fmt(fmt) "%s: " fmt, __func__
dynamic debug can add __func__ to each output
with +f so I think this prefixing with %s, __func__
is unnecessary.
I do think
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
is fairly standard, (though that can be added by
dynamic_debug as well with -m)
For example, without dynamic debug enabled
but with DEBUG #defined and KBUILD_MODNAME
I could get in dmesg:
aio: ENOMEM: nr_events too high
instead of
ioctx_alloc: ENOMEM: nr_events too high
and I think that's more intelligible.
These messages are not emitted by default, only
when specifically enabled with dynamic_debug or
adding #define DEBUG to the sources or -DDEBUG
to the Makefile
