- * Lock statistics structure for access, possibly only on this CPU.
- *
- * The statistics struct may be allocated with per-CPU structures for
- * efficient concurrent update (usually only on server-wide stats), or
- * as a single global struct (e.g. for per-client or per-job statistics),
- * so the required locking depends on the type of structure allocated.
- *
- * For per-CPU statistics, pin the thread to the current cpuid so that
- * will only access the statistics for that CPU.  If the stats structure
- * for the current CPU has not been allocated (or previously freed),
- * allocate it now.  The per-CPU statistics do not need locking since
- * the thread is pinned to the CPU during update.
- *
- * For global statistics, lock the stats structure to prevent concurrent update.
- *
- * \param[in] stats	statistics structure to lock
- * \param[in] opc	type of operation:
- *			LPROCFS_GET_SMP_ID: "lock" and return current CPU index
- *				for incrementing statistics for that CPU
- *			LPROCFS_GET_NUM_CPU: "lock" and return number of used
- *				CPU indices to iterate over all indices
- * \param[out] flags	CPU interrupt saved state for IRQ-safe locking
- *
- * \retval cpuid of current thread or number of allocated structs
- * \retval negative on error (only for opc LPROCFS_GET_SMP_ID + per-CPU stats)
