Comment 3 Mike Pagano gentoo-dev 2015-10-02 15:23:48 UTC 
Masked 4.1.9
Released 4.1.9-r1 with fix.
Upgrade and profit.
Comment 4 Manfred Knick 2015-10-03 10:54:59 UTC 
(In reply to Mike Pagano from comment #3)

Mike: Thanks a lot!

I guess you have read that Holger Hoffstätte requested this patch 
to be included into the pending 4.1.10 by Greg:

. . . https://lkml.org/lkml/2015/10/2/109

Thus, it may be that already to the next minor,
it should not be applied any more.
Comment 5 Thomas Deutschmann (RETIRED) gentoo-dev 2015-10-03 19:27:31 UTC 
Just for the records: The patch is not included in 4.1.10.
