From e6f856008d2364a16610d6269b6b38503d5e41a4 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Wed, 6 Oct 2021 08:59:52 -0500 Subject: gfs2: split glock instantiation off from do_promote Before this patch, function do_promote had a section of code that did the actual instantiation. This patch splits that off into its own function, gfs2_instantiate, which prepares us for the next patch that will use that function.
