I understand you and you do not have to be sorry.
Actually, this is rather me who have to apologize for the time taken by thi=
s=20
bad patch... Sorry about it.
Regarding the problem, maybe the following patch may solve the troublesome=

patch:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?
id=3D926fe783c8a64b33997fec405cf1af3e61aed441
I will investigate, but for curiosity purpose only and I totally understand=
