From cda37124f4e95ad5ccb11394a5802b0972668b32 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sat, 25 Mar 2017 21:15:37 -0700 Subject: fs: constify tree_descr arrays passed to simple_fill_super() simple_fill_super() is passed an array of tree_descr structures which describe the files to create in the filesystem's root directory. Since these arrays are never modified intentionally, they should be 'const' so that they are placed in .rodata and benefit from memory protection. This patch updates the function signature and all users, and also constifies tree_descr.name.
