From 064284c6cc20a8866db613f5832f548ee8c5e081 Mon Sep 17 00:00:00 2001 From: Lucas Wei Date: Fri, 18 Mar 2022 15:14:01 +0800 Subject: fs: sysfs_emit: Remove PAGE_SIZE alignment check For kernel releases older than 4.20, using the SLUB alloctor will cause this alignment check to fail as that allocator did NOT align kmalloc allocations on a PAGE_SIZE boundry. Remove the check for these older kernels as it is a false-positive and causes problems on many devices.
