Roger Pau Monné 1f13d75ccb xen-blkback: only read request operation from shared ring once ... A compiler may load a switch statement value multiple times, which could be bad when the value is in memory shared with the frontend. When converting a non-native request to a native one, ensure that src->operation is only loaded once by using READ_ONCE(). This is part of XSA155.
