Please let me know how it goes! I was able to rebase this on linux-next which has Paul's changes and ran it with: root@kpsingh:~# cat /proc/cmdline console=ttyS0,115200 root=/dev/sda rw nokaslr rcupdate.rcu_task_enqueue_lim=4 The warning about the nested spinlock in the raw spin locked section is also gone and I don't see any other warnings. Will send the rebased series after doing a few more checks. - KP > > Thanx, Paul
