3 * aio_subsys.h
4 * Interaction with AIO as a subsystem, rather than actually issuing AIO
5 *
6 * This header is for AIO related functionality that's being called by files
7 * that don't perform AIO, but interact with the AIO subsystem in some
8 * form. E.g. postmaster.c and shared memory initialization need to initialize
9 * AIO but don't perform AIO.
