            Bug ID: 1882
           Summary: volatile not needed with atomics
           Product: DPDK
           Version: 25.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: core
          Assignee: dev at dpdk.org
          Reporter: amardeepjk at gmail.com
  Target Milestone: ---

When we use atomic in c why are we using volatile.

Is it just for old compilers/ pre c11 versions?

typedef struct __rte_capability("spinlock") {
        volatile RTE_ATOMIC(int) locked; /**< lock status 0 = unlocked, 1 =
locked */
} rte_spinlock_t;

Can i raise a patch to remove it ?
