Man page 9 : scsi_allocate_command

scsi_allocate_command - get a fully allocated SCSI command

struct scsi_cmnd * scsi_allocate_command(gfp_t  gfp_mask );

gfp_mask
    allocation mask

This function is for use outside of the normal host based pools. It allocates the relevant command and takes an additional reference on the pool it used. This function *must* be paired with scsi_free_command which also has the identical mask, otherwise the free pool counts will eventually go wrong and youAqll trigger a bug.

This function should *only* be used by drivers that need a static command allocation at start of day for internal functions.
