      sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes · 91a69029

      Well, first of all, I don't want to change so many files either.
      
      What I do:
      Adding a new parameter "struct bin_attribute *" in the
      .read/.write methods for the sysfs binary attributes.
      
      In fact, only the four lines change in fs/sysfs/bin.c and
      include/linux/sysfs.h do the real work.
      But I have to update all the files that use binary attributes
      to make them compatible with the new .read and .write methods.
      I'm not sure if I missed any. :(
      
      Why I do this:
      For a sysfs attribute, we can get a pointer pointing to the
      struct attribute in the .show/.store method,
      while we can't do this for the binary attributes.
      I don't know why this is different, but this does make it not
      so handy to use the binary attributes as the regular ones.
      So I think this patch is reasonable. :)
      
      Who benefits from it:
      The patch that exposes ACPI tables in sysfs
      requires such an improvement.
      All the table binary attributes share the same .read method.
      Parameter "struct bin_attribute *" is used to get
      the table signature and instance number which are used to
      distinguish different ACPI table binary attributes.
      
      Without this parameter, we need to offer different .read methods
      for different ACPI table binary attributes.
      This is impossible as there are various ACPI tables on different
      platforms, and we don't know what they are until they are loaded.

      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.

      merge things properly.)
