[PATCH 05/17] lpfc: Rework remote port lock handling

James Smart
2020-11-15T19:27:16Z

[-- Attachment #1: Type: text/plain, Size: 77655 bytes --]

Currently the discovery layers within the driver use the scsi midlayer
host_lock to access node-specific structures. This can contend with the
io path and is too coarse of a lock.

Rework the driver so that it uses a lock specific to the remote port node
structure when accessing the structure contents. A few of the changes
brought out spots were some slightly reorganized routines worked better.
