From 5bf33f04eb5c3e6c55988046c88a5986430c7b4a Mon Sep 17 00:00:00 2001 From: Mateusz Nosek Date: Mon, 30 Dec 2019 20:16:28 +0100 Subject: fs/kernfs/dir.c: Clean code by removing always true condition Previously there was an additional check if variable pos is not null. However, this check happens after entering while loop and only then, which can happen only if pos is not null. Therefore the additional check is redundant and can be removed.
