Number of inline loops to get a shared lock
If a shared VM lock cannot be acquired directly, the following retriescan be configured:
a) Wait for the lock while blocking it. An attempt is made to acquirethe lock within a loop.
b) Release the occupied work process temporarily and then try to acquirethe lock again. From a VM perspective, this also takes places within aloop.
The parameter vmcj/rollout_lock_loops defines the number of loop passesin b).
