[ Upstream commit cd4d6b0bcd51580efda9ae54ab7b2d630b4147dc ]
The only place where the command was sent as SYNC is during
init and this is not really critical. This change is required
for replacing RS mutex with a spinlock (in the subsequent patch),
since SYNC comamnd requres sleeping and thus the flow cannot
be done when holding a spinlock.
