This patch is motivated by a response in the thread: Re: [PATCH 0/5]stop normal completion path entering a timeout req by Jianchao Wang . It generalizes the error injection of blk_abort_request() to use scsi_debug's "every_nth" mechanism.

2018-07-19scsi: hisi_sas: Fix the failure of recovering PHY from STP link timeoutXiaofei Tan
There is an issue that link reset can't recover PHY when STP link timeout. Because current process of enabling PHY for v3 hw will wait last transmission done. The time of one transmission depends IO size, disk model and so on. Normally, it should be shorter than 50ms. But the last transmission could be never done for some abnormal scenarios, such as STP link timeout. This patch is to fix the issue. Check PHY status after starting process of enabling PHY for 50ms. If the PHY is still active, we disable it forcibly by PHY reset. Of course, we need to clear the PHY reset bit when enable PHY. Besides, the function disable_phy_v3_hw() should not be suitable to call in interrupts for hilink bug for this 50ms delay. Then, we do link reset for hilink bug directly. The change is that we don't clear the invalid dword count register. This is better. Because we should not clear such error count while not saved.

When calling either fc_rport_logon() or fc_rport_logoff() during rport list traversal we cannot use the RCU list traversal, as either of these functions will be taking a mutex. So we need to partially revert commit a407c593398c to take the disc mutex during traversal. We should, however, continue to use krefs to ensure that the rport object will not be freed from under us.
