Applied.
Note, for bug fixes, lets start adding a "Fixes" tag (like the Linux
kernel does).
For instance, I'm adding this:
Fixes: c70227ebb264 ("kernel-shark-qt: Add Plugin event handlers to session.")
> Signed-off-by: Yordan Karadzhov <ykaradzhov@xxxxxxxxxx>
The format is, 12 characters of the sha1 of the commit that the patch
is fixing, followed by the title of the commit in: ("<commit-title>")
This way, if distros start supporting "stable" versions, they can see
if they should backport a patch or not.
Thanks!
