[PATCH v2 1/3] libkmod: add a library notice log level print

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When you use pass the -v argument to modprobe we bump
the log level from the default modprobe log level of
LOG_WARNING (4) to LOG_NOTICE (5), however the library
only has avaiable to print:

 #define DBG(ctx, arg...) kmod_log_cond(ctx, LOG_DEBUG, ## arg)
 #define INFO(ctx, arg...) kmod_log_cond(ctx, LOG_INFO, ## arg)
 #define ERR(ctx, arg...) kmod_log_cond(ctx, LOG_ERR, ## arg)

LOG_INFO (6) however is too high of a level for it to be
effective at printing anything when modprobe -v is passed.
And so the only way in which modprobe -v can trigger the
library to print a verbose message is to use ERR() but that
always prints something and we don't want that in some
situations.

We need to add a new log level macro which uses LOG_NOTICE (5)
for a "normal but significant condition" which users and developers
can use to look underneath the hood to confirm if a situation is
happening.
