Series | accel/tcg/plugin: Fix inject_mem_cb rw masking | expand |
Thanks for catching this Richard. I did the same mistake in plugins/core.c as well, could you fix it as well as part of this patch? For complement, rw are enums, R is 0b01, W is 0b10, and RW is 0b11, thus it work as expected with &.
