2018-09-26block, scsi: Change the preempt-only flag into a counterBart Van Assche1-4/+7
The RQF_PREEMPT flag is used for three purposes: - In the SCSI core, for making sure that power management requests are executed even if a device is in the "quiesced" state. - For domain validation by SCSI drivers that use the parallel port. - In the IDE driver, for IDE preempt requests. Rename "preempt-only" into "pm-only" because the primary purpose of this mode is power management. Since the power management core may but does not have to resume a runtime suspended device before performing system-wide suspend and since a later patch will set "pm-only" mode as long as a block device is runtime suspended, make it possible to set "pm-only" mode from more than one context. Since with this change scsi_device_quiesce() is no longer idempotent, make that function return early if it is called for a quiesced queue.

2018-09-26block: Move power management code into a new source fileBart Van Assche3-0/+3
Move the code for runtime power management from blk-core.c into the new source file blk-pm.c. Move the corresponding declarations from <linux/blkdev.h> into <linux/blk-pm.h>. For CONFIG_PM=n, leave out the declarations of the functions that are not used in that mode. This patch not only reduces the number of #ifdefs in the block layer core code but also reduces the size of header file <linux/blkdev.h> and hence should help to reduce the build time of the Linux kernel if CONFIG_PM is not defined.

This makes debugging the actual reason for the broken request cmd_flags pretty hard as the system is down before it's able to write out debugging data on the serial console or the trace buffer.

Then get the adapter reset request again, so driver does scsi_block_requests, this will cause the scsi_add_device get hung until we unblock.

2018-09-17scsi: sd: Contribute to randomness when running rotational deviceXuewei Zhang1-0/+3
Currently a scsi device won't contribute to kernel randomness when it uses blk-mq. Since we commonly use scsi on rotational device with blk-mq, it make sense to keep contributing to kernel randomness in these cases. This is especially important for virtual machines. commit b5b6e8c8d3b4 ("scsi: virtio_scsi: fix IO hang caused by automatic irq vector affinity") made all virtio-scsi device to use blk-mq, which does not contribute to randomness today. So for a virtual machine only having virtio-scsi disk (which is common), it will simple stop getting randomness from its disks in today's implementation. With this patch, if the above VM has rotational virtio-scsi device, then it can still benefit from the entropy generated from the disk.

A recent change added some MDS processing in the lpfc_drain_txq routine that relies on the fcp_wq being allocated. For nvmet operation the fcp_wq is not allocated because it can only be an nvme-target. When the original MDS support was added LS_MDS_LOOPBACK was defined wrong, (0x16) it should have been 0x10 (decimal value used for hex setting). This incorrect value allowed MDS_LOOPBACK to be set simultaneously with LS_NPIV_FAB_SUPPORTED, causing the driver to crash when it accesses the non-existent fcp_wq. Correct the bad value setting for LS_MDS_LOOPBACK. Fixes: ae9e28f36a6c ("lpfc: Add MDS Diagnostic support.")
