scsi_allocate_command — get a fully allocated SCSI command
struct scsi_cmnd * scsi_allocate_command ( | gfp_t gfp_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 you'll trigger a bug.
This function should *only* be used by drivers that need a static command allocation at start of day for internal functions.
