An earlier fix changed the print format specifier for adapter->bios_addr to use %lX. However, the integer is a u32 so the fix was wrong. Fix this by using the correct %X format specifier.

Existing blogic_msg() invocations do not appear to overrun its internal buffer of a fixed length of 100, which would cause stack corruption, but it's easy to miss with possible further updates and a fix is cheap in performance terms, so limit the output produced into the buffer by using vscnprintf() rather than vsprintf().

Allow UFS suspend/resume callbacks to run in parallel with other suspend/resume callbacks. This can recoup dozens of milliseconds on the resume path if UFS hardware needs to be powered back on. Suspending and resuming asynchronously is safe to do so long as the driver callbacks only depend on resources made available by either a) parent devices or b) devices explicitly marked as suppliers with device_link_add.

The lpfc_sli4_nvmet_xri_aborted() routine takes out the abts_buf_list_lock and traverses the buffer contexts to match the xri. Upon match, it then takes the context lock before potentially removing the context from the associated buffer list. This violates the lock hierarchy used elsewhere in the driver of locking context, then the abts_buf_list_lock - thus a possible deadlock. Resolve by: after matching, release the abts_buf_list_lock, then take the context lock, and if to be deleted from the list, retake the abts_buf_list_lock, maintaining lock hierarchy. This matches same list lock hierarchy as elsewhere in the driver Link: https://lore.kernel.org/r/20210730163309.25809-1-jsmart2021@gmail.comReported-by:

Move the sg_timeout and sg_reserved_size fields into the bsg_device and scsi_device structures as they have nothing to do with generic block I/O. Note that these values are now separate for bsg vs. SCSI device node access, but that just matches how /dev/sg vs the other nodes has always behaved.

cdrom_read_cdda_bpc() relies on sending SCSI command to the low level driver using a REQ_OP_SCSI_IN request. This isn't generic block layer functionality, so move the actual low-level code into the sr driver and call it through a new read_cdda_bpc method in the cdrom_device_ops structure. With this the CDROM code does not have to pull in scsi_normalize_sense() and depend on CONFIG_SCSI_COMMON. Link: https://lore.kernel.org/r/20210730072752.GB23847%40lst.deTested-by:
