From 89154dd5313f774d3a592451360b78442571b1f8 Mon Sep 17 00:00:00 2001 From: Michel Lespinasse <walken@google.com> Date: Mon, 8 Jun 2020 21:33:29 -0700 Subject: mmap locking API: convert mmap_sem call sites missed by coccinelle Convert the last few remaining mmap_sem rwsem calls to use the new mmap locking API. These were missed by coccinelle for some reason (I think coccinelle does not support some of the preprocessor constructs in these files ?)
