core: Global timer-wheel
Instantiate a process wide global instance of the timer wheel data structure. Spawning glusterfs* process with option arg "--global-timer-wheel" instantiates a global instance of timer-wheel under global context (->ctx). Translators can make use of this process wide instance [via a call to glusterfs_global_timer_wheel()] instead of maintaining an instance of their own and possibly consuming more memory. Linux kernel too has a single instance of timer wheel where subsystems such as IO, networking, etc.. make use of. Bitrot daemon would be early consumers of this: bitrot translator instances for multiple volumes would track objects belonging to their respective bricks in this global expiry tracking data structure. This is also a first step to move GlusterFS timer mechanism to use timer-wheel. > Change-Id: Ie882df607e07acaced846ea269ebf1ece306d6ae > BUG: 1170075 > Signed-off-by: Venky Shankar <vshankar@redhat.com> > Reviewed-on: http://review.gluster.org/10380 > Tested-by: NetBSD Build System > Reviewed-by: Vijay Bellur <vbellur@redhat.com> > Tested-by: Gluster Build System <jenkins@build.gluster.com> Change-Id: I35c840daa9996a059699f8ea5af54c76ede7e09c Signed-off-by: Venky Shankar <vshankar@redhat.com> Signed-off-by: Gaurav Kumar Garg <ggarg@redhat.com> BUG: 1220041 Reviewed-on: http://review.gluster.org/10716 Tested-by: Gluster Build System <jenkins@build.gluster.com>
