This pull request contains one patch to fix the return value of cpuset's cgroups interface function, which used to always return -ENODEV for the writes on the "memory_pressure_enabled" file. The fix is available in the following branch git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git for-3.11-fixes for you to fetch changes up to a903f0865a190f8778c73df1a810ea6e25e5d7cf: cpuset: fix the return value of cpuset_write_u64() (2013-08-13 10:54:40 -0400) Thanks. ---------------------------------------------------------------- Li Zefan (1): cpuset: fix the return value of cpuset_write_u64() kernel/cpuset.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/kernel/cpuset.c b/kernel/cpuset.c index e565778..010a008 100644 --- a/kernel/cpuset.c +++ b/kernel/cpuset.c @@ -1608,11 +1608,13 @@ static int cpuset_write_u64(struct cgroup *cgrp, struct cftype *cft, u64 val) { struct cpuset *cs = cgroup_cs(cgrp); cpuset_filetype_t type = cft->private; - int retval = -ENODEV; + int retval = 0; mutex_lock(&cpuset_mutex); - if (!is_cpuset_online(cs)) + if (!is_cpuset_online(cs)) { + retval = -ENODEV; goto out_unlock; + } switch (type) { case FILE_CPU_EXCLUSIVE: -- tejun
