MEMPOOL_ALLOC(9)                    Memory Management in Linux                   MEMPOOL_ALLOC(9)



NAME
       mempool_alloc - allocate an element from a specific memory pool

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

ARGUMENTS
       pool
           pointer to the memory pool which was allocated via mempool_create.

       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.)

NOTE
       using __GFP_ZERO is not supported.
