The quilt patch titled Subject: kernel: make taskstats available from all net namespaces has been removed from the -mm tree. Its filename was kernel-make-taskstats-available-from-all-net-namespaces.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: xu xin <xu.xin16@xxxxxxxxxx> Subject: kernel: make taskstats available from all net namespaces If getdelays runs in a non-init network namespace, it will fail in getting delayacct stats even if it has privilege of root user, which seems to be not very reasonable. We can simply reproduce this by executing commands: unshare -n getdelays -d -p <pid> I don't think net namespace should be an obstacle to the normal execution of getdelay function. So let's make it available from all net namespaces.
