If you were subscribed to the remoteproc mailing list you would see that every
two weeks I send an email that lists the patchsets in my queue and the order in
which I intend to review them.
That helps people know what kind of traffic maintainers currently deal with. If
a patchset is not listed on that email it is likely because it slipped through
the cracks, as it is the case with this set. You did not notify me and as such
it was impossible for me to know about it.
Last but not least I do not recall you reviewing a single patchset on this list
since the beginning of the year, which automatically negate your right to
complain about how long it takes for patches to be reviewed.
