block: remove skd driver

2021-02-04T14:45:32+00:00

The STEC S1220 PCIe SSD cards are EOL since 2014 and not supported by
the vendor anymore. As the skd driver for this SSD is starting to cause
problems with improvements to the block layer, stop supporting it in
newer kernel versions.

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

blk-mq: move failure injection out of blk_mq_complete_request

2020-06-24T15:15:57+00:00

Move the call to blk_should_fake_timeout out of blk_mq_complete_request
and into the drivers, skipping call sites that are obvious error
handlers, and remove the now superflous blk_mq_force_complete_rq helper.
This ensures we don't keep injecting errors into completions that just
terminate the Linux request after the hardware has been reset or the
command has been aborted.

Merge tag 'v5.2-rc6' into for-5.3/block

2019-07-01T14:16:08+00:00

Merge 5.2-rc6 into for-5.3/block, so we get the same page merge leak
fix. Otherwise we end up having conflicts with future patches between
for-5.3/block and master that touch this area. In particular, it makes
the bio_full() fix hard to backport to stable.

block: skd_main.c: Remove call to memset after dma_alloc_coherent

2019-06-29T15:42:51+00:00

In commit af7ddd8a627c
("Merge tag 'dma-mapping-4.21' of git://git.infradead.org/users/hch/dma-mapping"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.

cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37+00:00

We already need to zero out memory for dma_alloc_coherent(), as such
using dma_zalloc_coherent() is superflous. Phase it out.

This change was generated with the following Coccinelle SmPL patch:

@ replace_dma_zalloc_coherent @
expression dev, size, data, handle, flags;
@@

-dma_zalloc_coherent(dev, size, handle, flags)
+dma_alloc_coherent(dev, size, handle, flags)

Add a retries field to the internal request structure instead, which gets
set to zero on the first submission.
