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

block: fold cmd_type into the REQ_OP_ space

2017-01-31T21:00:44Z

Instead of keeping two levels of indirection for requests types, fold it all into the operations. The little caveat here is that previously cmd_type only applied to struct request, while the request and bio op fields were set to plain REQ_OP_READ/WRITE even for passthrough operations. Instead this patch adds new REQ_OP_* for SCSI passthrough and driver private requests, althought it has to add two for each so that we can communicate the data in/out nature of the request.

block: make scsi_request and scsi ioctl support optional

2017-01-31T17:53:05Z

We only need this code to support scsi, ide, cciss and virtio. And at least for virtio it's a deprecated feature to start with. This should shrink the kernel size for embedded device that only use, say eMMC a bit. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

Replace with globally

2016-12-24T19:46:01Z

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

paride: make 'verbose' parameter an 'int' again

2016-03-15T23:55:16Z

gcc-6.0 found an ancient bug in the paride driver, which had a "module_param(verbose, bool, 0);" since before 2.6.12, but actually uses it to accept '0', '1' or '2' as arguments: drivers/block/paride/pd.c: In function 'pd_init_dev_parms': drivers/block/paride/pd.c:298:29: warning: comparison of constant '1' with boolean expression is always false [-Wbool-compare] #define DBMSG(msg) ((verbose>1)?(msg):NULL) In 2012, Rusty did a cleanup patch that also changed the type of the variable to 'bool', which introduced what is now a gcc warning. This changes the type back to 'int' and adapts the module_param() line instead, so it should work as documented in case anyone ever cares about running the ancient driver with debugging.

mm, page_alloc: rename __GFP_WAIT to __GFP_RECLAIM

2015-11-07T01:50:42Z

__GFP_WAIT was used to signal that the caller was in atomic context and could not sleep. Now it is possible to distinguish between true atomic context and callers that are not willing to sleep. The latter should clear __GFP_DIRECT_RECLAIM so kswapd will still wake. As clearing __GFP_WAIT behaves differently, there is a risk that people will clear the wrong flags. This patch renames __GFP_WAIT to __GFP_RECLAIM to clearly indicate what it does -- setting it allows all reclaim activity, clearing them prevents it.
