2020-03-16scsi: hisi_sas: Use dev_err() in read_iost_itct_cache_v3_hw()Luo Jiaxing1-1/+2
The print of pr_err() does not come with device information, so replace it with dev_err(). Also improve the grammar in the message.

2020-03-11scsi: core: avoid repetitive logging of device offline messagesEwan D. Milne2-2/+9
Large queues of I/O to offline devices that are eventually submitted when devices are unblocked result in a many repeated "rejecting I/O to offline device" messages. These messages can fill up the dmesg buffer in crash dumps so no useful prior messages remain. In addition, if a serial console is used, the flood of messages can cause a hard lockup in the console code. Introduce a flag indicating the message has already been logged for the device, and reset the flag when scsi_device_set_state() changes the device state.

2020-03-11scsi: docs: convert arcmsr_spec.txt to ReSTMauro Carvalho Chehab5-576/+910
This file had its own peculiar style, not following any other files inside the Kernel (as far as I saw). Had to do a number of changes here, starting by removing the two leading asterisks from each line, adding table and literal block markups and changing whitespace and blank lines. The end result is that (IMHO), it is now a lot easier to read it as a text file, while producing a good html output.

2020-03-11scsi: iscsi: Add support for asynchronous iSCSI session destructionFrank Mayhar3-0/+40
iSCSI session destruction can be arbitrarily slow, since it might require network operations and serialization inside the SCSI layer. This patch adds a new user event to trigger the destruction work asynchronously, releasing the rx_queue_mutex as soon as the operation is queued and before it is performed. This change allows other operations to run in other sessions in the meantime, removing one of the major iSCSI bottlenecks for us. To prevent the session from being used after the destruction request, we remove it immediately from the sesslist. This simplifies the locking required during the asynchronous removal.
