2022-08-31scsi: lpfc: Fix unsolicited FLOGI receive handling during PT2PT discoveryJames Smart
During a stress offline/online test in PT2PT topology, target rediscovery can fail with a specific target vendor array. When the HBA transitions to online mode it is possible to receive an unsolicited FLOGI before processing the Link Up event. The received FLOGI will set the defer_flogi_acc_flag, which instructs the driver to wait until it transmits its own FLOGI before ACKing the received FLOGI. In this failure scenario, the link up processing clears the set defer_flogi_acc_flag before we have sent out the FLOGI. As the target has the higher WWPN and is responsible for sending the PLOGI, the target is stuck waiting for its FLOGI_ACC that the driver will never send. Remove the clear of defer_flogi_acc_flag from Link Up event processing. In this stress test case, the defer_flogi_acc_flag is cleared during the Link Down event processing anyways.

There is the following quirk to bypass "WB Flush" in Write Booster. - UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL If this quirk is not set, there is no knob that can control "WB Flush". There are three flags that control Write Booster Feature: 1. WB ON/OFF 2. WB Hibern Flush ON/OFF (implicitly) 3. WB Flush ON/OFF (explicit) The sysfs attribute that controls the WB was implemented. (1) In the case of "Hibern Flush", it is always good to turn on. Control may not be required. (2) Finally, "Flush" may be necessary because the Auto-Hibern8 is not supported in a specific environment. So the sysfs attribute that controls this is necessary.

Provide clk-scaling feature in MediaTek UFS platforms. MediaTek platform supports clk-scaling by switching parent clock mux of UFSHCI main clocks: ufs_sel.

2022-08-13afs: Enable multipage folio supportDavid Howells
Enable multipage folio support for the afs filesystem. Support has already been implemented in netfslib, fscache and cachefiles and in most of afs, but I've waited for Matthew Wilcox's latest folio changes. Note that it does require a change to afs_write_begin() to return the correct subpage. This is a "temporary" change as we're working on getting rid of the need for ->write_begin() and ->write_end() completely, at least as far as network filesystems are concerned - but it doesn't prevent afs from making use of the capability.
