2020-03-27block: simplify queue allocationChristoph Hellwig
Current make_request based drivers use either blk_alloc_queue_node or blk_alloc_queue to allocate a queue, and then set up the make_request_fn function pointer and a few parameters using the blk_queue_make_request helper. Simplify this by passing the make_request pointer to blk_alloc_queue, and while at it merge the _node variant into the main helper by always passing a node_id, and remove the superfluous gfp_mask parameter. A lower-level __blk_alloc_queue is kept for the blk-mq case. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-27bcache: pass the make_request methods to blk_queue_make_requestChristoph Hellwig
bcache is the only driver not actually passing its make_request methods to blk_queue_make_request, but instead just sets them up manually a little later. Make bcache follow the common way of setting up make_request based queues. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>

2020-03-27block: add a blk_mq_init_queue_data helperChristoph Hellwig
This allows a driver to pass a queuedata member before ->init_hctx is called. null_blk currently open codes this logic, but I'd rather have it in the core to ease future maintainance.

2020-03-27USB: cdc-acm: restore capability check orderMatthias Reichl
commit b401f8c4f492c ("USB: cdc-acm: fix rounding error in TIOCSSERIAL") introduced a regression by changing the order of capability and close settings change checks. When running with CAP_SYS_ADMIN setting the close settings to the values already set resulted in -EOPNOTSUPP. Fix this by changing the check order back to how it was before.

gcc 10 will default to -fno-common, which causes this error at link time: (.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here This is because both dtc-lexer as well as dtc-parser define the same global symbol yyloc. Before with -fcommon those were merged into one defintion. The proper solution would be to to mark this as "extern", however that leads to: dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls] 26 | extern YYLTYPE yylloc; | ^~~~~~ In file included from dtc-lexer.l:24: dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here 127 | extern YYLTYPE yylloc; | ^~~~~~ cc1: all warnings being treated as errors which means the declaration is completely redundant and can just be dropped.

2020-03-26net: ks8851-ml: Fix IO operations, againMarek Vasut
This patch reverts 58292104832f ("net: ks8851-ml: Fix 16-bit IO operation") and edacb098ea9c ("net: ks8851-ml: Fix 16-bit data access"), because it turns out these were only necessary due to buggy hardware. This patch adds a check for such a buggy hardware to prevent any such mistakes again. While working further on the KS8851 driver, it came to light that the KS8851-16MLL is capable of switching bus endianness by a hardware strap, EESK pin. If this strap is incorrect, the IO accesses require such endian swapping as is being reverted by this patch. Such swapping also impacts the performance significantly. Hence, in addition to removing it, detect that the hardware is broken, report to user, and fail to bind with such hardware.

2020-03-26afs: Fix unpinned address list during probingDavid Howells
When it's probing all of a fileserver's interfaces to find which one is best to use, afs_do_probe_fileserver() takes a lock on the server record and notes the pointer to the address list. It doesn't, however, pin the address list, so as soon as it drops the lock, there's nothing to stop the address list from being freed under us.
