SYNOPSIS

10

ARGUMENTS

12       pool
13           pointer to the memory pool which was allocated via mempool_create.

DESCRIPTION

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