Subject: [PATCH 0/2] function_graph: ftrace_graph_ret_addr(); there can be only one!
Date: Mon, 10 Jun 2024 23:09:34 -0400 [thread overview]
Message-ID: <20240611030934.162955582@goodmis.org> (raw)
I noticed a slight bug in ftrace_graph_ret_addr() for when
HAVE_FUNCTION_GRAPH_RET_ADDR_PTR was defined and fixed it up.
I then noticed it was buggy when not defined. Looking for an
architecture that did not have it defined, I couldn't find any.
So I removed it.

function_graph: Everyone uses HAVE_FUNCTION_GRAPH_RET_ADDR_PTR, remove it
