From a15d0b365e9bbf04dacb44fbe69d15f6594460e1 Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Wed, 7 Mar 2012 17:34:36 -0800 Subject: [PATCH] staging: android: persistent_ram: add notrace to persistent_ram_write Add the notrace attribute to persistent_ram_write and the non-ecc functions that it calls to allow persistent_ram to be used for ftracing (only when ecc is disabled).
