Subject: [PATCH 0/6] cpuset: convert to new cpumask API
Date: Wed, 31 Dec 2008 16:34:46 +0800 [thread overview]
Message-ID: <495B2EA6.7010808@cn.fujitsu.com> (raw)
This patchset converts cpuset to use new cpumask API, and thus
remove on stack cpumask_t to reduce stack usage.
Before:
# cat kernel/cpuset.c include/linux/cpuset.h | grep -c cpumask_t
21
After:
# cat kernel/cpuset.c include/linux/cpuset.h | grep -c cpumask_t
0
The patchset is based on mmotm 2008-12-30-16-05.
[PATCH 1/6] cpuset: remove on stack cpumask_t in cpuset_sprintf_cpulist()
[PATCH 2/6] cpuset: remove on stack cpumask_t in cpuset_can_attach()
[PATCH 3/6] cpuset: convert cpuset_attach() to use cpumask_var_t
[PATCH 4/6] cpuset: don't allocate trial cpuset on stack
[PATCH 5/6] cpuset: convert cpuset->cpus_allowed to cpumask_var_t
[PATCH 6/6] cpuset: remove remaining pointers to cpumask_t
