[Qemu-devel] [PATCH] aio / timers: De-document -clock

[Markus Armbruster <armbru@redhat.com>]

Commit 6d32717 "aio / timers: Remove alarm timers" has issues:

1. It silently ignores -clock for backward compatibility.
Incompatible change: -clock help no longer terminates the program.
Tolerable.

2. Failed to update option documentation.  In particular, -help still
advises users to try -clock help for available timers.  Drop all
documentation on -clock.

3. The 'query-alarm-clock' example in docs/writing-commands.txt no
longer works, and needs to be redone.  Can't do that right now, so I
just stick in a FIXME.

 For this example we will write the query-alarm-clock command, which returns
 information about QEMU's timer alarm. For more information about it, please
 check the "-clock" command-line option.
