From 744e6c8ada5d612353a42ce8cd8323dd2364a70d Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 9 Mar 2022 10:16:12 -0800 Subject: xfs: constify xfs_name_dotdot The symbol xfs_name_dotdot is a global variable that the xfs codebase uses here and there to look up directory dotdot entries. Currently it's a non-const variable, which means that it's a mutable global variable. So far nobody's abused this to cause problems, but let's use the compiler to enforce that.
