2018-03-08Documentation/cdrom: fix German sharp s in LaTexRandy Dunlap
Apparently the LaTex abbreviation for the German "sharp s" (ß) (Unicode U+00DF) has changed from {\sz} to {\ss}. With {\sz}, I get this error at line 1016 (line number after another patch): ! Undefined control sequence. l.1016 ...nel~2.0. Further thanks to Heiko Ei{\sz }feldt, This is fixed by changing the {\sz} to {\ss}.

2017-10-12documentation: Update ide-cd documentation to reflect CONFIG_BLK_DEV_HD_IDE ↵Finn Thain
removal CONFIG_BLK_DEV_HD_IDE was removed in commit 80aa31cb460d ("ide: remove CONFIG_BLK_DEV_HD_IDE config option (take 2)") but the ide-cd documentation was not updated and still asks users to disable it, which is misleading and involves a fruitless search.

2017-02-14cdrom: Make device operations read-onlyKees Cook
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 <keescook@chromium.org> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Jens Axboe <axboe@fb.com>
