| 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. |
