From 6bdcadea75768bbd1cd8f6f13011978e1e19a53b Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Wed, 15 Jan 2020 05:31:38 +0100 Subject: gfs2: Minor gfs2_lookup_by_inum cleanup Use a zero no_formal_ino instead of a NULL pointer to indicate that any inode generation number will qualify: a valid inode never has a zero no_formal_ino.
