mempool_create — create a memory pool
mempool_t * mempool_create ( | int | min_nr, |
| mempool_alloc_t * | alloc_fn, | |
| mempool_free_t * | free_fn, | |
| void * | pool_data); |
min_nrthe minimum number of elements guaranteed to be allocated for this pool.
alloc_fnuser-defined element-allocation function.
free_fnuser-defined element-freeing function.
pool_dataoptional private data available to the user-defined functions.
this function creates and allocates a guaranteed size, preallocated
memory pool. The pool can be used from the mempool_alloc and mempool_free
functions. This function might sleep. Both the alloc_fn and the free_fn
functions might sleep - as long as the mempool_alloc function is not called
from IRQ contexts.
