RDMA tree follows standard kernel development process, which means that
we start rdma-rc and rdma-next right after (or week later) the merge window
is closed. The exact timing depends on the quality of Linus's master
after merge window ends.
After these branches are created, rdma-rc is used for bug fixes and
rdma-next is used for new features.
We are relatively lax about the quality of bug fixes up to -rc4. After that,
fixes are going under more scrutiny and can/will be applied to rdma-next
if they are not critical.
The rdma-next branch is for features and bug fixes that are not
critical.

Yes, it can be merged to rdma-next later, but you shouldn't rely on it.
It is happening when we are required to merge something from later -rxX,
which already contains your rdma-rc patch. We are not merging
"explicitly" patches from rdma-rc to rdma-next.

Linus's announcements are on LKML:
https://lore.kernel.org/all/CAHk-=wjV_O2g_K19McjGKrxFxMFDqex+fyGcKc3uac1ft_O2gg@xxxxxxxxxxxxxx/
And semi-joke-semi-real schedule is here:
http://deb.tandrin.de/phb-crystal-ball.htm
It is based on assumption that kernel cycle is 7-8 weeks.
