Subject: [RFC PATCH 0/9] Export information needed by the LTTng kernel tracer
Date: Thu, 9 Apr 2020 15:35:34 -0400 [thread overview]
Message-ID: <20200409193543.18115-1-mathieu.desnoyers@efficios.com> (raw)
Recently commit 0bd476e6c6 "kallsyms: unexport kallsyms_lookup_name()
and kallsyms_on_each_symbol()" was merged upstream. As discussed
previously [1], LTTng-modules (a GPL kernel tracer module) currently
uses kallsyms to lookup some missing symbols.
This patch set integrates the required changes to the kernel code
wherever those changes are generally useful, and adds a few GPL-exports
targeting the information currently missing so LTTng modules can be
entirely free of kallsyms.
Feedback is welcome,
Thanks,
Mathieu
