Subject: [git pull] vfs_mkobj() and mqueue-related stuff

	mqueue and bpf go through rather painful and similar contortions to
create objects in their dentry trees.  Provide a primitive for doing that
without abusing ->mknod(), switch bpf and mqueue to it.
	Another mqueue-related thing that has ended up in that branch is
on-demand creation of internal mount (based upon the work of Giuseppe Scrivano).

  mqueue: switch to on-demand creation of internal mount (2018-01-05 11:54:37 -0500)

----------------------------------------------------------------
Al Viro (9):
      new primitive: vfs_mkobj()
      bpf_obj_do_pin(): switch to vfs_mkobj(), quit abusing ->mknod()
      mqueue: switch to vfs_mkobj(), quit abusing ->d_fsdata
      move dentry_open() calls up into do_mq_open()
      mqueue: fold mq_attr_ok() into mqueue_get_inode()
      do_mq_open(): move all work prior to dentry_open() into a helper
      mqueue: clean prepare_open() up
      tidy do_mq_open() up a bit
      mqueue: switch to on-demand creation of internal mount
