Subject: [PATCH 28/52] tools lib symbols: Introduce kallsyms__is_function()
Date: Wed,  2 May 2018 12:19:18 -0300	[thread overview]
Message-ID: <20180502151942.20542-29-acme@kernel.org> (raw)
In-Reply-To: <20180502151942.20542-1-acme@kernel.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Out of symbol_type__is_a(type, MAP__FUNCTION), which is the only variant
used so far, useful in a kallsyms library and one more step in ditching
the MAP__FUNCTION/VARIABLE split.
