325 * kvm_s390_inject_prog_cond - conditionally inject a program check
326 * @vcpu: virtual cpu
327 * @rc: original return/error code
328 *
329 * This function is supposed to be used after regular guest access functions
330 * failed, to conditionally inject a program check to a vcpu. The typical
331 * pattern would look like
332 *
333 * rc = write_guest(vcpu, addr, data, len);
334 * if (rc)
335 * return kvm_s390_inject_prog_cond(vcpu, rc);
336 *
337 * A negative return code from guest access functions implies an internal error
338 * like e.g. out of memory. In these cases no program check should be injected
339 * to the guest.
340 * A positive value implies that an exception happened while accessing a guest's
341 * memory. In this case all data belonging to the corresponding program check
342 * has been stored in vcpu->arch.pgm and can be injected with
343 * kvm_s390_inject_prog_irq().
344 *
345 * Returns: - the original @rc value if @rc was negative (internal error)
346 * - zero if @rc was already zero
347 * - zero or error code from injecting if @rc was positive
348 * (program check injected to @vcpu)
