+Subject: init/Kconfig: remove USELIB syscall by default

+The uselib syscall has been long deprecated.  There's no need to keep this

+Get rid of redundant assignments which end up in values not being

+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.
