v4:
* Rebased & retested for easy review and merge
* No code changes
v3:
* Squashed Paolo's fixes and added his patch to avoid locking in
timer_pending()
v2:
* Rebased onto qemu.git/master following the merge of Alex's AioContext timers
The purpose of these patches is to eventually allow device models to set and
cancel timers without holding the global mutex. When the device model runs in
a vcpu thread and the iothread processes timers, the
QEMUTimerList->active_timers must be protected from concurrent access.
Patch 1 is a clean-up.
Patch 2 is the entire change needed to protect ->active_timers.
Patch 3 makes timer_pending() run without a lock.
Paolo Bonzini (1):
qemu-timer: do not take the lock in timer_pending
Stefan Hajnoczi (2):
qemu-timer: drop outdated signal safety comments
qemu-timer: make qemu_timer_mod_ns() and qemu_timer_del() thread-safe
