kactive_blk_num (K) is incremented on block close. last_kactive_blk_num (L) is set to match K on block open and each timer. So the only time that they differ is if a block is closed in tpacket_rcv and no new block could be opened. So the origin check L==K in timer callback only skip the case 'no new block to open'. If we remove L==K check, it will make prb_curr_blk_in_use check earlier, which will not cause any side effect. Signed-off-by: Xin Zhao <redacted>
