here is an excerpt: [EMAIL PROTECTED] root]# mount -t container -ocpuset cpuset /containers/ [EMAIL PROTECTED] root]# ls /containers/ cpu_exclusive memory_pressure mems tasks cpus memory_pressure_enabled notify_on_release mem_exclusive memory_spread_page releasable memory_migrate memory_spread_slab release_agent [EMAIL PROTECTED] root]# mkdir /containers/1 [EMAIL PROTECTED] root]# echo 0 > /containers/1/mems [EMAIL PROTECTED] root]# echo 0 > /containers/1/cpus [EMAIL PROTECTED] root]# sh sh-2.05b# echo $$ > /containers/1/tasks sh-2.05b# cat /containers/1/tasks 4325 4326 sh-2.05b# exit [EMAIL PROTECTED] root]# ls /containers/1/tasks /containers/1/tasks [EMAIL PROTECTED] root]# rm -rf /containers/1 rm: cannot remove `/containers/1/memory_spread_slab': Operation not permitted rm: cannot remove `/containers/1/memory_spread_page': Operation not permitted rm: cannot remove `/containers/1/memory_pressure': Operation not permitted rm: cannot remove `/containers/1/memory_migrate': Operation not permitted rm: cannot remove `/containers/1/mem_exclusive': Operation not permitted rm: cannot remove `/containers/1/cpu_exclusive': Operation not permitted rm: cannot remove `/containers/1/mems': Operation not permitted rm: cannot remove `/containers/1/cpus': Operation not permitted rm: cannot remove `/containers/1/releasable': Operation not permitted rm: cannot remove `/containers/1/notify_on_release': Operation not permitted rm: cannot remove `/containers/1/tasks': Operation not permitted Ah, I see the second time I typed 'ls /containers/1/tasks' instead of cat. When I then used cat, the file was empty, and I got an oops just like Pavel reported. I bet if I solve the problem he reported, then I solve my problem :) thanks, -serge - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
