    Subject[PATCH 4.14 14/22] fs: sysfs_emit: Remove PAGE_SIZE alignment check
    Date
    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.
