Subject: Re: [PATCH v2] drivers: staging: lustre: Use 'force_die' instead
 of 'die' to avoid compiling issue


For drivers/staging/lustre/lustre/include/lustre_sec.h:391:

 - staging tree: use '\t   ' between 'die' and '('.

 - linux-next tree: use '   ' between 'die' and '('.

So the patch made under linux-next tree, can not apply to staging-next
or staging tree.


Thanks.
