Subject[PATCH 14/22] staging: lustre: obd: add callback for llog_cat_process_or_fork
Date
From: Alexander Boyko <alexander.boyko@seagate.com>

Currently llog_process_or_fork() is hard coded to
always pass the function pointer llog_cat_process_cb().
Change llog_cat_process_or_fork() to pass in any
function pointer which will allow us more options
for llog_cat callback routines in the future.
