Very valid question. For some reason Konstantin has not sended pr to
Linus. I have also address my concern that pr is not yet sended and he
will make very massive "patch dumb" to rc6/rc7. See thread [1]. There is
about 50-70 patch already which he will send to rc6/rc7. I have get also
impression that patches which are not yet even applied to ntfs3 tree [2]
will be also sended to rc6/rc7. There is lot of refactoring and new
algorithms which imo are not rc material. I have sended many message to
Konstantin about this topic, but basically ignored.
Basically we do not have anything for next merge window and every patch
will be sended for 5.15.
