From 062fb903895a035ed382a0d3f9b9d459b2718217 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Wed, 26 Jul 2023 22:23:43 +0200 Subject: [PATCH] gfs2: Rename gfs2_lookup_{ simple => meta } Function gfs2_lookup_simple() is used for looking up inodes in the metadata directory tree, so rename it to gfs2_lookup_meta() to closer match its purpose. Clean the function up a little on the way.
