mempool_alloc: allocate an element from a specific memory pool

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.
