From 2949e8427af3bb74a1e26354cb68c1700663c827 Mon Sep 17 00:00:00 2001 From: Lukas Bulwahn Date: Tue, 24 Aug 2021 13:12:59 +0200 Subject: fs: clean up after mandatory file locking support removal Commit 3efee0567b4a ("fs: remove mandatory file locking support") removes some operations in functions rw_verify_area(). As these functions are now simplified, do some syntactic clean-up as follow-up to the removal as well, which was pointed out by compiler warnings and static analysis. No functional change.
