Subject: move unsafe global rkey handling to the RDMA core V2
Date: Mon, 5 Sep 2016 12:56:15 +0200 [thread overview]
Message-ID: <1473072981-2035-1-git-send-email-hch@lst.de> (raw)
This fairly simply series adds support to ib_alloc_pd to create the unsafe
global rkey in the IB core, and then switches over all ULPs to use that
functionality instead of using ib_get_dma_mr directly, and consequently
removes ib_get_dma_mr now that all global registrations are done in the
core code.
The advantage is that abuses of ib_get_dma_mr are more easily prevented,
and use of the global unsafe rkey is more visible and auditable.
I'm also pondering removing the get_dma_mr methods and moving the global
registrations into the ->alloc_pd methods, but I'll need to investigate
how that will work out first.
Changes since V1:
- keep a pointer to the pd in the srp_target_port strucure
- fix a typo in a patch description
