drivers/cdrom: improved ioctl for media change detection

2021-09-15T02:05:26+00:00

The current implementation of the CDROM_MEDIA_CHANGED ioctl relies on
global state, meaning that only one process can detect a disc change
while the ioctl call will return 0 for other calling processes afterwards
(see bug 213267).

This introduces a new cdrom ioctl, CDROM_TIMED_MEDIA_CHANGE, that
works by maintaining a timestamp of the last detected disc change instead
of a boolean flag: Processes calling this ioctl command can provide
a timestamp of the last disc change known to them and receive
an indication whether the disc was changed since then and the updated
timestamp.

I considered fixing the buggy behavior in the original
CDROM_MEDIA_CHANGED ioctl but that would require maintaining state
for each calling process in the kernel, which seems like a worse
solution than introducing this new ioctl.

docs: cdrom-standard.rst: get rid of uneeded UTF-8 chars

2021-05-11T17:00:17+00:00

This file was converted from a LaTeX one. The conversion used
some UTF-8 characters at the literal blocks. Replace them
by normal ASCII characters.

2020-08-11T16:43:06+00:00

"The capability fags" should be "The capability flags".

In rst markup, a incorrect markup expression is causing bad rendering in
Sphinx output. Replace the erroneous single quote by a backquote.

cdrom: remove the unused cdrom_media_changed function

2020-07-08T22:20:01+00:00

As well as the ->media_changed method.  All these are left over from
before the drivers were switched over to the check_events scheme.

docs: add some directories to the main documentation index

2019-07-15T14:03:03+00:00

The contents of those directories were orphaned at the documentation
body.

While those directories could likely be moved to be inside some guide,
I'm opting to just adding their indexes to the main one, removing the
:orphan: and adding the SPDX header.

For the drivers, the rationale is that the documentation contains
a mix of Kernelspace, uAPI and admin-guide. So, better to keep them on
separate directories, as we've be doing with similar subsystem-specific
docs that were not split yet.

For the others, well... I'm too lazy to do the move. Also, it
seems to make sense to keep at least some of those at the main
dir (like kbuild, for example). In any case, a latter patch
could do the move.

docs: ide: convert docs to ReST and rename to *.rst

2019-06-14T20:21:18+00:00

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

docs: cdrom: convert docs to ReST and rename to *.rst

2019-06-14T20:20:46+00:00

The stuff there is almost already at ReST format. A
conversion for them is trivial: just add a missing titles
and fix some scape codes for them to match ReST syntax.

While here, rename the cdrom-standard.txt, with was converted
from LaTeX to ReST on the previous patch, and add it to the
index file.

At its new index.rst, let's add a :orphan: while this is not linked to

docs: cdrom-standard.tex: convert from LaTeX to ReST

2019-06-14T20:20:43+00:00

This is the only LaTeX documentation file inside the documentation.

Instead of having a Latex document directly there, convert
it to ReST format, as this is the format we're using for docs.

For now, let's keep the extension as .txt in order to avoid
warnings when building the documentation with Sphinx.

The next patch patch will rename it to .rst and add it to the
building system.

Drop all 00-INDEX files from Documentation/

2018-09-09T21:08:58+00:00

This is a respin with a wider audience (all that get_maintainer returned)
and I know this spams a *lot* of people. Not sure what would be the correct
way, so my apologies for ruining your inbox.

The 00-INDEX files are supposed to give a summary of all files present
in a directory, but these files are horribly out of date and their
usefulness is brought into question. Often a simple "ls" would reveal
the same information as the filenames are generally quite descriptive as
a short introduction to what the file covers (it should not surprise
anyone what Documentation/sched/sched-design-CFS.txt covers)

A few years back it was mentioned that these files were no longer really
needed, and they have since then grown further out of date, so perhaps
it is time to just throw them out.

A short status yields the following _outdated_ 00-INDEX files, first
counter is files listed in 00-INDEX but missing in the directory, last
is files present but not listed in 00-INDEX.

List of outdated 00-INDEX:
Documentation: (4/10)
Documentation/sysctl: (0/1)
Documentation/timers: (1/0)
Documentation/blockdev: (3/1)
Documentation/w1/slaves: (0/1)
Documentation/locking: (0/1)
Documentation/devicetree: (0/5)
Documentation/power: (1/1)
Documentation/powerpc: (0/5)
Documentation/arm: (1/0)
Documentation/x86: (0/9)
Documentation/x86/x86_64: (1/1)
Documentation/scsi: (4/4)
Documentation/filesystems: (2/9)
Documentation/filesystems/nfs: (0/2)
Documentation/cgroup-v1: (0/2)
Documentation/kbuild: (0/4)
Documentation/spi: (1/0)
Documentation/virtual/kvm: (1/0)
Documentation/scheduler: (0/2)
Documentation/fb: (0/1)
Documentation/block: (0/1)
Documentation/networking: (6/37)
Documentation/vm: (1/3)

Then there are 364 subdirectories in Documentation/ with several files that
are missing 00-INDEX alltogether (and another 120 with a single file and no
00-INDEX).

I don't really have an opinion to whether or not we /should/ have 00-INDEX,
but the above 00-INDEX should either be removed or be kept up to date. If
we should keep the files, I can try to keep them updated, but I rather not
if we just want to delete them anyway.

As a starting point, remove all index-files and references to 00-INDEX and
see where the discussion is going.
