Hi Eugene, It's fine to use both lfht resize and destroy from URCU QSBR, because we explicitly mark the threads "offline" (saving the old state), and restore the original state, at the beginning and end of those functions.
However, calls to cds_lfht_resize() and cds_lfht_destroy are considered as an explicit quiescent state in URCU QSBR, therefore, don't expect your RCU read-side critical section to extend across those 2 calls.
