From b7eefcf11f3fb1703ddfa075d4f4bc30b9c50eb4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 9 Apr 2024 16:37:35 +0200 Subject: scsi: core: Add a device_configure method to the host template This is a version of ->slave_configure that also takes a queue_limits structure that the caller applies, and thus allows drivers to reconfigure the queue using the atomic queue limits API. In the long run it should also replace ->slave_configure entirely as there is no need to have two different methods here, and the slave name in addition to being politically charged also has no basis in the SCSI standards or the kernel code.
