----------------------------------------------------
Hi,

The discussion about RWQ table patch revealed incosistency with use of
usecnt, complex unwind flows without any reason and difference between
write() and ioctl() paths.

This series extends infrastructure to be consistent, reliable and
predicable in regards of commit/desotry uobject.

Thanks
