This is mostly updates of the usual suspects: lpfc, qla2xxx, hisi_sas, megaraid_sas, pm80xx, mpt3sas, be2iscsi, hpsa. and a host of minor updates. There's no major behaviour change or additions to the core in all of this, so the potential for regressions should be small (biggest potential being in the scsi error handler changes).

* This defines the scsi logging feature. It is a means by which the user can
|
|
* select how much information they get about various goings on, and it can be
|
|
* really useful for fault tracing. The logging word is divided into 10 3-bit
|
|
* bitfields, each of which describes a loglevel. The division of things is
|
|
* somewhat arbitrary, and the division of the word could be changed if it
|
|
* were really needed for any reason. The numbers below are the only place
|
|
* where these are specified. For a first go-around, 3 bits is more than
|
|
* enough, since this gives 8 levels of logging (really 7, since 0 is always
|
|
* off). Cutting to 2 bits might be wise at some point.
