+Subject: fs: sysfs_emit: Remove PAGE_SIZE alignment check
+
+From: Lucas Wei <lucaswei@google.com>
+
+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.
