This reverts commit 7a6bbc28. The offending commit tried to suppress a double "Starting disk" message for some drivers, but instead started spamming the log with bogus messages every five seconds: [ 311.798956] sd 0:0:0:0: [sda] Starting disk [ 316.919103] sd 0:0:0:0: [sda] Starting disk [ 322.040775] sd 0:0:0:0: [sda] Starting disk [ 327.161140] sd 0:0:0:0: [sda] Starting disk [ 332.281352] sd 0:0:0:0: [sda] Starting disk [ 337.401878] sd 0:0:0:0: [sda] Starting disk [ 342.521527] sd 0:0:0:0: [sda] Starting disk [ 345.850401] sd 0:0:0:0: [sda] Starting disk [ 350.967132] sd 0:0:0:0: [sda] Starting disk [ 356.090454] sd 0:0:0:0: [sda] Starting disk ... on machines that do not actually stop the disk on runtime suspend (e.g. the Qualcomm sc8280xp CRD with UFS).

There is a deadlock when runtime suspend waits for the flush of RTC work, and the RTC work calls ufshcd_rpm_get_sync() to wait for runtime resume.

The device does not come online when the target port is online. There were multiple RSCNs indicating multiple devices were affected. Driver is in the process of finishing a fabric scan. A new RSCN (device up) arrived at the tail end of the last fabric scan. Driver mistakenly thinks the new RSCN is being taken care of by the previous fabric scan, where this notification is cleared and not acted on. The laser needs to be blinked again to get the device to show up. To prevent driver from accidentally clearing the RSCN notification, each RSCN is given a generation value. A fabric scan will scan for that generation(s). Any new RSCN arrive after the scan start will have a new generation value. This will trigger another scan to get latest data. The RSCN notification flag will be cleared when the scan is associate to that generation. Reported-by:

Eric Biggers <ebiggers@kernel.org> says: Add support for Flash Memory Protector (FMP), which is the inline encryption hardware on Exynos and Exynos-based SoCs. Specifically, add support for the "traditional FMP mode" that works on many Exynos-based SoCs including gs101. This is the mode that uses "software keys" and is compatible with the upstream kernel's existing inline encryption framework in the block and filesystem layers. I plan to add support for the wrapped key support on gs101 at a later time. Tested on gs101 (specifically Pixel 6) by running the 'encrypt' group of xfstests on a filesystem mounted with the 'inlinecrypt' mount option.

Since the nonstandard inline encryption support on Exynos SoCs requires that raw cryptographic keys be copied into the PRDT, it is desirable to zeroize those keys after each request to keep them from being left in memory. Therefore, add a quirk bit that enables the zeroization. We could instead do the zeroization unconditionally. However, using a quirk bit avoids adding the zeroization overhead to standard devices.
