[Qemu-devel] [PATCH 0/8] RCUification of the memory API, part 1

[Paolo Bonzini <pbonzini@redhat.com>]

These are the minimal changes to adopt RCU and use it in memory_region_find
(and hence in virtio-blk-dataplane).  Looks big, but two thirds of it
is documentation and tests.

Please review! :)

Paolo

Jan Kiszka (1):
  memory: remove assertion on memory_region_destroy

Paolo Bonzini (7):
  tls: require compiler support for __thread
  rcu: add rcu library
  rcu: add rcutorture
  rcu: allow nesting of rcu_read_lock/rcu_read_unlock
  rcu: add call_rcu
  memory: protect current_map by RCU
  memory: avoid ref/unref in memory_region_find
