Subject: sched: convert struct (sys_)sched_setaffinity() to cpumask_var_t.
X-Git-Tag: v2.6.29-rc1~538^2~41
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5a16f3d30ca4e3f166d691220c003066a14e32b5;p=pandora-kernel.git

sched: convert struct (sys_)sched_setaffinity() to cpumask_var_t.

Impact: stack usage reduction

Dynamically allocating cpumasks (when CONFIG_CPUMASK_OFFSTACK) saves
space on the stack.  cpumask_var_t is just a struct cpumask for
!CONFIG_CPUMASK_OFFSTACK.

Note the removal of the initializer of new_mask: since the first thing
we did was "cpus_and(new_mask, new_mask, cpus_allowed)" I just changed
that to "cpumask_and(new_mask, in_mask, cpus_allowed);".
