I get also a result like the following together with the software "Linux next-20151126". ;-)

elfring@Sonne:~/Projekte/Linux/next-patched> LANG=C git apply ~/Projekte/Bau/Linux/scripts/Coccinelle/deletions1/next/20151102/Flicken/0003-staging-lustre-Less-function-calls-in-class_register.patch
error: patch failed: drivers/staging/lustre/lustre/obdclass/genops.c:214
error: drivers/staging/lustre/lustre/obdclass/genops.c: patch does not apply


Do you try this update suggestion out without integrating the corresponding previous
update suggestion "Delete unnecessary checks before two function calls"
where I proposed to remove extra checks before a few calls of the function "kobject_put"
(which seems to matter for the patch hunk in the shown error message)?
https://lkml.org/lkml/2015/11/5/276
https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1013635.html

Would you like to reject the first update step from this patch series
so that I need to adapt my approach to your software design decision?

Regards,
Markus
