SCSI_ALLOCATE_COMMAN(9) SCSI mid layer SCSI_ALLOCATE_COMMAN(9)
NAME
scsi_allocate_command - get a fully allocated SCSI command
SYNOPSIS
struct scsi_cmnd * scsi_allocate_command(gfp_t gfp_mask);
ARGUMENTS
gfp_mask
allocation mask
DESCRIPTION
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.
