* Merge branch 'chcpu' of ↵Karel Zak2011-08-311-1/+1
|\ | | | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/heiko/util-linux * 'chcpu' of git://git.kernel.org/pub/scm/linux/kernel/git/heiko/util-linux: chcpu: new tool cpuset: add option to allow cpulist_parse() to fail
| * cpuset: add option to allow cpulist_parse() to failHeiko Carstens2011-08-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a preparation patch for chcpu. If a cpu should be added to a cpu_set where the cpu doesn't fit into the cpu_set this got silently ignored. Since the cpu-list is user space provided it should be checked if cpus are specified that are completely out of range of the system. In order to do that add a parameter which specifies if cpulist_parse() should fail if it parses a cpu-list with "impossible" cpus. The current callers have been converted so they behave like before.

| | | | | | | | | | | | | | | | | | | | | | | Add a new '-a' option to view/modify the CPU affinity for an entire group of threads belonging to a given PID. We create two new functions, print_affinity() and do_taskset() for code simplification. Example: zeus@jilguero:~/src/util-linux/schedutils$ ./taskset -a -p 01 3142 pid 3142's current affinity mask: 2 pid 3142's new affinity mask: 1 pid 3164's current affinity mask: 2 pid 3164's new affinity mask: 1 pid 854's current affinity mask: 2 pid 854's new affinity mask: 1 [kzak@redhat.com: - clean up - move variables to struct taskset] Signed-off-by: Davidlohr Bueso <dave@gnu.org> Tested-by: Jonathan Gonzalez <zeus@gnu.org> Signed-off-by: Karel Zak <kzak@redhat.com>
