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

2019-06-14T20:21:04+00:00

The conversion is actually:
  - add blank lines and indentation 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.

dm delay: add flush as a third class of IO

2018-07-27T19:24:19+00:00

Add a new class for dm-delay that delays flush requests.  Previously,
flushes were delayed as writes, but it caused problems if the user
needed to create a device with one or a few slow sectors for the purpose
of testing - all flushes would be forwarded to this device and delayed,
and that skews the test results.  Fix this by allowing to select 0 delay
for flushes.

Documentation/device-mapper: s/getsize/getsz/

2016-12-14T09:54:27+00:00

According to `man blockdev':

  --getsize
         Print device size (32-bit!) in sectors.
         Deprecated in favor of the --getsz option.
  ...
  --getsz
         Get size in 512-byte sectors.

Hence, occurrences of `--getsize' should be replaced with `--getsz',
which this commit has achieved as follows:

  $ cd "$repo"
  $ git grep -l -e --getsz

  Documentation/device-mapper/log-writes.txt
  Documentation/device-mapper/striped.txt
  Documentation/device-mapper/switch.txt
  $ cd Documentation/device-mapper
  $ sed -i s/getsize/getsz/g *

dm delay: document that offsets are specified in sectors

2015-10-31T23:06:05+00:00

Only delay params are mentioned in delay.txt.
Mention offsets just like documents for linear and flakey do.

dm: delay target

2007-05-09T19:30:47+00:00

New device-mapper target that can delay I/O (for testing).  Reads can be
separated from writes, redirected to different underlying devices and delayed
by differing amounts of time.
