examples/qos_sched: fix core mask overflow
Masking of core mask was incorrect. Instead of using 1U for shifting, it should be using 1LU as the result is assigned to uint64. CID 375859: Potentially overflowing expression "1U << app_main_core" with type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "uint64_t" (64 bits, unsigned). Coverity issue: 375859 Fixes: de3cfa2c9823 ("sched: initial import") Cc: stable@dpdk.org Signed-off-by: Megha Ajmera <megha.ajmera@intel.com> Acked-by: Morten Brørup <mb@smartsharesystems.com>
