From 1a829ff2a6c37187ff8020488e84ec392cb94854 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 12 Jun 2019 16:55:38 +0200 Subject: ceph: no need to check return value of debugfs_create functions When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. This cleanup allows the return value of the functions to be made void, as no logic should care if these files succeed or not. Cc: "Yan, Zheng" Cc: Sage Weil Cc: Ilya Dryomov Cc: "David S.
