Name

mempool_alloc — allocate an element from a specific memory pool

Synopsis

void * mempool_alloc (mempool_t * pool,
 gfp_t gfp_mask);
 

Arguments

mempool_t * pool

pointer to the memory pool which was allocated via mempool_create.

gfp_t gfp_mask

the usual allocation bitmask.

Description

this function only sleeps if the alloc_fn function sleeps or returns NULL. Note that due to preallocation, this function *never* fails when called from process contexts. (it might fail if called from an IRQ context.)
