2021-07-15Documentation: sysrq: convert to third personCengiz Can1-5/+7
Two parts of the sysrq documentation have sentences written from a first person's point of view. Documentation is generally written from a third person's view in a formal way. Convert those senteces to be less personal and generic.

2021-03-15Documentation: sysrq: update description about sysrq crashGao Xiang1-2/+2
After commit 8341f2f222d7 ("sysrq: Use panic() to force a crash"), a crash was not generated by dereferencing a NULL pointer anymore. Let's update documentation as well to make it less misleading.

2020-10-02tty/sysrq: Extend the sysrq_key_table to cover capital lettersAndrzej Pietrasiewicz1-0/+2
All slots in sysrq_key_table[] are either used, reserved or at least commented with their intended use. This patch adds capital letter versions available, which means adding 26 more entries. For already existing SysRq operations the user presses Alt-SysRq-<key>, and for the newly added ones Alt-Shift-SysRq-<key>.

2020-05-15tty/sysrq: constify the sysrq APIEmil Velikov1-5/+5
The user is not supposed to thinker with the underlying sysrq_key_op. Make that explicit by adding a handful of const notations.

2020-04-07Documentation: sysrq: fix RST formattingAlyssa Ross1-9/+11
"On x86" and "On SPARC" are now definition list terms, like "On PowerPC", "On other", and "On all". The Credits list is now a bulleted list, like lots of Credits lists in other files. This prevents the list from becoming a single long, unpunctuated sentence in the generated documentation. I also did a couple of other tiny readability improvements to the "How do I use the magic SysRq key?" section while I was there.

2019-09-06Documentation: sysrq: don't recommend 'S' 'U' before 'B'Adam Borowski1-11/+9
This advice is obsolete and slightly harmful for filesystems from this millenium: any modern filesystem can handle unexpected crashes without requiring fsck -- and on the other hand, trying to write to the disk when the kernel is in a bad state risks introducing corruption. For ext2, any unsafe shutdown meant widespread breakage, but it's no longer a reasonable filesystem for any non-special use.

2016-10-24docs-rst: create an user's manual bookMauro Carvalho Chehab1-0/+289
Place README, REPORTING-BUGS, SecurityBugs and kernel-parameters on an user's manual book. As we'll be numbering the user's manual, remove the manual numbering from SecurityBugs. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
