Synopsis

   #include <sys/types.h>
   #include <sys/ddi.h>
   
   void
   met_ds_iodone(met_disk_stats_t *dsp, uint b_flags, ulong bytes)

Description

met_ds_iodone updates disk statistics when a read or write request completes.

Arguments

dsp: Pointer to a met_disk_stats_t statistics structure.
b_flags: The contents of the buffer header flags field.
bytes: The number of bytes transferred by the read or write request.

Return values

None.

Usage

When a read or write request completes and before the next request is sent, the driver must call met_ds_iodone to update I/O completion statistics.

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

met_ds_iodone should be protected from interrupts.

Context and synchronization

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

Hardware applicability

All

Version applicability

ddi: 5, 5mp, 6, 6mp, 7, 7mp, 7.1, 7.1mp, 8, 8mp
