2025-07-09rv: Let the reactors take care of buffersNam Cao
Each RV monitor has one static buffer to send to the reactors. If multiple errors are detected simultaneously, the one buffer could be overwritten. Instead, leave it to the reactors to handle buffering.

2023-04-13rv/reactor: remove MODULE_LICENSE in non-modulesNick Alcock
Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.
