sys/kern/subr_bus.c
5589	Why ignoring the error? I believe even SBUF_FIXEDLEN would get into an error state on overflow of the buffer.
sys/kern/subr_rman.c
1031	IMO it is worth extracting the same code into a small helper function and calling it twice, instead of copying.
1052	There should be a blank line after the local variables block. There and in several other places in the patch.
