Subject: [PATCHSET] FUSE: extend FUSE to support more operations, take #2

Hello, all.

This patchset is the second take of extend-FUSE patchset.  Changes
from the last take[L] are...

* add-include-protectors and implement-nonseekable-open already merged
  and thus dropped from this patchset.

* pass-nonblock-flag-to-client dropped in favor of fi.flags &
  O_NONBLOCK test.

* FUSE_MINOR moved to miscdevice.h

* ioctl support updated to include restricted mode where only well
  formed ioctls are supported and no retry is necesary or allowed.
  All FUSE servers are forced to use restricted mode ioctl.

* Per file unique kernel handle, fuse_file->kh, is added and used to
  match poll notification to its file.  This lifts the requirement
  that the FUSE server should supply unique fh to make use of poll.

* Other small fixes and updated to the current tree.

This patchset contains the following five patches.

 0001-fuse-move-FUSE_MINOR-to-miscdevice.h
 0002-FUSE-implement-ioctl-support
 0003-FUSE-add-file-kernel-handle
 0004-FUSE-implement-unsolicited-notification
 0005-FUSE-implement-poll-support

and is on top of

  master (ee2f6cc7f9ea2542ad46070ed62ba7aa04d08871)
+ [1] poll-allow-f_op_poll-to-sleep-take-2
+ [2] add-cdev_release-and-convert-cdev_alloc-to-use-it
