rtapi_slab - RTAPI wrappers for linux kernel functionality
#include <rtapi_slab.h>

*rtapi_kmalloc(size_t size, gfp_t g);

void rtapi_kfree(void*);
In kernel space, each rtapi_xxx or RTAPI_XXX identifier is mapped to the underlying kernel functionality, if available.
In userspace, or in kernels where the underlying functionality is not provided by a kernel, generally another implementation — possibly with reduced functionality — is provided. (For example, the userspace implementation for rtapi_device_register always succeeds)
Call only from within init/cleanup code, not from realtime tasks. This function is not available from non-realtime code.
As in Linux.
