ms/extable: Consolidate *kernel_text_address() functions Author: Steven Rostedt (VMware) <rost...@goodmis.org> backported upstream commit 9aadde91b3c035413c806619beb3e3ef6e697953 The functionality between kernel_text_address() and _kernel_text_address() is the same except that _kernel_text_address() does a little more (that function needs a rename, but that can be done another time). Instead of having duplicate code in both, simply have _kernel_text_address() calls kernel_text_address() instead. This is marked for stable because there's an RCU bug that can happen if one of these functions gets called while RCU is not watching. That fix depends on this fix to keep from having to write the fix twice. Cc: sta...@vger.kernel.org Fixes: 0be964be0 ("module: Sanitize RCU usage and locking") Acked-by: Paul E.
