This replaces the "shmem_size" and "shmem_init" callbacks in the IO methods table with the same ShmemCallback struct that we now use in other subsystems Reviewed-by: Ashutosh Bapat <ashutosh.bapat.oss@gmail.com> Reviewed-by: Matthias van de Meent <boekewurm+postgres@gmail.com> Reviewed-by: Daniel Gustafsson <daniel@yesql.se> Discussion: https://www.postgresql.org/message-id/CAExHW5vM1bneLYfg0wGeAa=52UiJ3z4vKd3AJ72X8Fw6k3KKrg@mail.gmail.com

* This header is for AIO related functionality that's being called by files
|
|
* that don't perform AIO, but interact with the AIO subsystem in some
|
|
* form. E.g. postmaster.c and shared memory initialization need to initialize
|
|
* AIO but don't perform AIO.
