From: Akash Goel <akash.goel@xxxxxxxxx> We are trying to reduce the time for which the global 'struct_mutex' is locked. Execbuffer ioctl is one place where it is generally held for the longest time. And sometimes because of this occasional glitches/flickers are being observed in 60 fps playback (due to miss of V-blank intervals) as page flip call is getting delayed because the 'struct_mutex' is already locked.
