block: don't set bounce limit in blk_init_queue

2017-06-27T18:13:45Z

Instead move it to the callers. Those that either don't use bio_data() or page_address() or are specific to architectures that do not support highmem are skipped. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

block: introduce new block status code type

2017-06-09T15:27:32Z

Currently we use nornal Linux errno values in the block layer, and while we accept any error a few have overloaded magic meanings. This patch instead introduces a new blk_status_t value that holds block layer specific status codes and explicitly explains their meaning. Helpers to convert from and to the previous special meanings are provided for now, but I suspect we want to get rid of them in the long run - those drivers that have a errno input (e.g. networking) usually get errnos that don't know about the special block layer overloads, and similarly returning them to userspace will usually return somethings that strictly speaking isn't correct for file system operations, but that's left as an exercise for later. For now the set of errors is a very limited set that closely corresponds to the previous overloaded errno values, but there is some low hanging fruite to improve it. blk_status_t (ab)uses the sparse __bitwise annotations to allow for sparse typechecking, so that we can easily catch places passing the wrong values.

scripts/spelling.txt: add "overide" pattern and fix typo instances

2017-03-10T01:01:09Z

Fix typos and add the following to the scripts/spelling.txt: overide||override While we are here, fix the doubled "address" in the touched line Documentation/devicetree/bindings/regulator/ti-abb-regulator.txt. Also, fix the comment block style in the touched hunks in drivers/media/dvb-frontends/drx39xyj/drx_driver.h.

cdrom: Make device operations read-only

2017-02-14T15:29:56Z

Since function tables are a common target for attackers, it's best to keep them in read-only memory. As such, this makes the CDROM device ops tables const. This drops additionally n_minors, since it isn't used meaningfully, and sets the only user of cdrom_dummy_generic_packet explicitly so the variables can all be const. Inspired by similar changes in grsecurity/PaX. Signed-off-by: Kees Cook Acked-by: David S. Miller Signed-off-by: Jens Axboe

Replace with globally

block: remove struct request buffer member

2014-04-15T20:03:02Z

This was used in the olden days, back when onions were proper yellow. Basically it mapped to the current buffer to be transferred. With highmem being added more than a decade ago, most drivers map pages out of a bio, and rq->buffer isn't pointing at anything valid. Convert old style drivers to just use bio_data(). For the discard payload use case, just reference the page in the bio. Signed-off-by: Jens Axboe

block_device_operations->release() should return void

2013-05-07T06:16:21Z

The value passed is 0 in all but "it can never happen" cases (and those only in a couple of drivers) *and* it would've been lost on the way out anyway, even if something tried to pass something meaningful. Just don't bother. Signed-off-by: Al Viro
