From 8992de4cec126c6703ece0747239d071dbce725f Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 20 Jan 2016 14:59:52 -0800 Subject: [PATCH] fat: constify fatent_operations structures The fatent_operations structures are never modified, so declare them as const. Done with the help of Coccinelle.
