Mask would remain and perhaps become a module
variable instead of a compile #define.

What is jffs2_debug? Do you mean JFFS2_DEBUG?
My intent was to remove JFFS2_<LEVEL> defines and uses.
These #defines add
"(%d) %s" ... task_pid_nr(current), __func__
which can be added if really necessary via pr_fmt
to generic pr_<level> uses.

I am not certain of the value for generic uses of
task_pid_nr in pr_notice,pr_err, or pr_info.

Dynamic debugging has the ability to optionally add
task_pid_vnr and __func__ to pr_debug output.
