docs: fix references to docs/devel/tracing.rst Commit e50caf4a5c ("tracing: convert documentation to rST") converted docs/devel/tracing.txt to docs/devel/tracing.rst. We still have several references to the old file, so let's fix them with the following command: sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt) Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20210517151702.109066-2-sgarzare@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

trace-events: Shorten file names in comments We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim. Delete the sub/dir/ part from these comments. Gets rid of several misspellings.

# announce.c
net/announce: Add optional ID Previously there was a single instance of the timer used by monitor triggered announces, that's OK, but when combined with the previous change that lets you have announces for subsets of interfaces it's a bit restrictive if you want to do different things to different interfaces. Add an 'id' field to the announce, and maintain a list of the timers based on id. This allows you to for example: a) Start an announce going on interface eth0 for a long time b) Start an announce going on interface eth1 for a long time c) Kill the announce on eth0 while leaving eth1 going.

migration: Switch to using announce timer Switch the announcements to using the new announce timer. Move the code that does it to announce.c rather than savevm because it really has nothing to do with the actual migration. Migration starts the announce from bh's and so they're all in the main thread/bql, and so there's never any racing with the timers themselves.
