met_ds_queued -- update disk statistics when a read or write request is added to the queue

Synopsis

   #include <sys/types.h>
   #include <sys/ddi.h>
   
   void
   met_ds_queued(met_disk_stats_t *dsp, uint_t b_flags)

met_ds_queued updates disk statistics when a read or write request is added to the driver queue.

None.

Just before a read or write request is added to the driver queue, the driver must call met_ds_queued.

The dsp parameter is a pointer to a met_disk_stats_t statistics structure which was allocated through a call to met_ds_alloc_stats(D3).

Refer to met_ds_dequeued(D3) man page if the enqueuing can fail.

met_ds_queued should be protected from interrupts.

Non-blockable, interrupt, user, or blockable context.
