Subject: [PATCH 0/5] uio hotplug support


Implement the ability to hotunplug a uio device while file handles
are still open without crashing.

I have written the code very carefully, and this survives my
basic testing.  So at the very least this is better than
what is present in uio today.

I have implemented the ``locking'' for hotunplug support in
a generic library, that should be reusable to make this
kind of support easier to add in other pieces of the kernel.

Eric W. Biederman (5):
      uio: Simplify the lifetime logic of struct uio_device.
      uio: Kill unused vma_count.
      uio: Remove unused uio_info mmap method.
      libunload: A library to help remove open files
      uio: Implement hotunplug support, using libunload
