Hello, Ingo, This series enables srcu_read_lock() and srcu_read_unlock to be used from interrupt handlers, which fixes a bug in KVM's use of SRCU in delivery of interrupts to guest OSes. These patches have been exposed to 0day Test Robot and to -next testing, have been tested by the KVM folks, and were posted to LKML: http://lkml.kernel.org/r/20170605220919.GA27820@xxxxxxxxxxxxxxxxxx These changes, based on v4.2-rc4, are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/urgent for you to fetch changes up to 1123a6041654e8f889014659593bad4168e542c2: srcu: Allow use of Classic SRCU from both process and interrupt context (2017-06-08 08:25:19 -0700) ---------------------------------------------------------------- Paolo Bonzini (2): srcu: Allow use of Tiny/Tree SRCU from both process and interrupt context srcu: Allow use of Classic SRCU from both process and interrupt context include/linux/srcu.h | 2 -- kernel/rcu/srcu.c | 5 ++--- kernel/rcu/srcutiny.c | 7 ++++--- kernel/rcu/srcutree.c | 5 ++--- 4 files changed, 8 insertions(+), 11 deletions(-)
