Subject: [PATCH v2 22/24] dyndbg: add print-class as trailing number to control output
Date: Sat, 13 Jun 2020 09:57:36 -0600 [thread overview]
Message-ID: <20200613155738.2249399-23-jim.cromie@gmail.com> (raw)
In-Reply-To: <20200613155738.2249399-1-jim.cromie@gmail.com>
This change adds trailing 0 for all existing callsites, and N>0 for
any uses of pr_debug_n().
subsequent patches add pr_debug_n(1) & pr_debug_n(2) to kset-example,
demonstrating that the callsite descriptors are getting initialized
properly by the *_cl adaptations done previously.
bash-5.0# modprobe kset-example
bash-5.0# grep -v '0$' control
[ 311.060809] dynamic_debug:ddebug_proc_open: called
samples/kobject/kset-example.c:80 [kset_example]foo_attr_store =_ "called" 2
samples/kobject/kset-example.c:59 [kset_example]foo_attr_show =_ "called" 1
