      fuse: introduce fuse_simple_request() helper · 7078187a
      Miklos Szeredi authored 
      The following pattern is repeated many times:

	req = fuse_get_req_nopages(fc);
	/* Initialize req->(in|out).args */
	fuse_request_send(fc, req);
	err = req->out.h.error;
	fuse_put_request(req);

Create a new replacement helper:

	/* Initialize args */
	err = fuse_simple_request(fc, &args);

In addition to reducing the code size, this will ease moving from the
complex arg-based to a simpler page-based I/O on the fuse device.

      fuse: hold inode instead of path after release · baebccbe
      Miklos Szeredi authored 
      path_put() in release could trigger a DESTROY request in fuseblk.  The
possible deadlock was worked around by doing the path_put() with
schedule_work().

This complexity isn't needed if we just hold the inode instead of the path.
Since we now flush all requests before destroying the super block we can be
sure that all held inodes will be dropped.

      fuse: flush requests on umount · 580640ba
      Miklos Szeredi authored 
      Use fuse_abort_conn() instead of fuse_conn_kill() in fuse_put_super().
This flushes and aborts requests still on any queues.  But since we've
already reset fc->connected, those requests would not be useful anyway and
would be flushed when the fuse device is closed.

Next patches will rely on requests being flushed before the superblock is
destroyed.

Use fuse_abort_conn() in cuse_process_init_reply() too, since it makes no
difference there, and we can get rid of fuse_conn_kill().

      fuse: don't wake up reserved req in fuse_conn_kill() · 0c4dd4ba
      Miklos Szeredi authored 
      Waking up reserved_req_waitq from fuse_conn_kill() doesn't make sense since
we aren't chaging ff->reserved_req here, which is what this waitqueue
signals.
