    sysfs: kill unnecessary attribute->owner · 7b595756
    Tejun Heo authored
    sysfs is now completely out of driver/module lifetime game.  After
    deletion, a sysfs node doesn't access anything outside sysfs proper,
    so there's no reason to hold onto the attribute owners.  Note that
    often the wrong modules were accounted for as owners leading to
    accessing removed modules.
    This patch kills now unnecessary attribute->owner.  Note that with
    this change, userland holding a sysfs node does not prevent the
    backing module from being unloaded.
    For more info regarding lifetime rule cleanup, please read the
    following message.
    (tweaked by Greg to not delete the field just yet, to make it easier to
    merge things properly.)
