Subject: [PATCH] arch/Kconfig: Update HAVE_RELIABLE_STACKTRACE description
Date: Mon, 20 Jan 2020 16:40:42 +0100
Message-ID: <20200120154042.9934-1-mbenes@suse.cz> (raw)

save_stack_trace_tsk_reliable() is not the only function providing the
reliable stack traces anymore. Architecture might define ARCH_STACKWALK
which provides a newer stack walking interface and has
arch_stack_walk_reliable() function. Update the description accordingly.
