Re: [Scst-devel] Changes for RHEL6?

[Hiroyuki S. <hir...@gm...>]

Hi

I tried to build scst on Scientific Linux release 6.0 x86_64

Please take a look attached files.
both files are header linux/sched.h

sched.h_scientific.h : Scientific Linux Header file
sched.h_kernel.h : 2.6.32.39 ( kernel.org )


set_cpus_allowed and set_cpus_allowed_ptr does not exists in the
header file in Scientific Linux.

But this is SMP kernel.
Linux localhost.localdomain 2.6.32-71.el6.x86_64 #1 SMP Tue Nov 23
06:49:13 CST 2010 x86_64 x86_64 x86_64 GNU/Linux
