I have just received this email. But since few days (or weeks) I have observed
a big latency on the LAKML. Sometime my emails were in the LAKML after 3 or 4
hours.

There is a filter which prevent to "hijack" a thread by changing the topic.
of course it is a problem for the patch set sent with git send-email. So for
this there is an exception if you have the word PATCH in your topic. But
it doesn't work with the work RFC. Maybe it is the word you have chosen. If
you are in this case then you can use [PATCH RFC ]
