- * As of July 2007, all known versions of the Linux kernel will sometimes
- * return EIDRM for a shmctl() operation when EINVAL is correct (it happens
- * when the low-order 15 bits of the supplied shm ID match the slot number
- * assigned to a newer shmem segment). We deal with this by assuming that
- * EIDRM means EINVAL in PGSharedMemoryIsInUse(). This is reasonably safe
- * since in fact Linux has no excuse for ever returning EIDRM; it doesn't
- * track removed segments in a way that would allow distinguishing them from
- * private ones. But someday that code might get upgraded, and we'd have
- * to have a kernel version test here.

- * Set the default wal_sync_method to fdatasync. With recent Linux versions,
- * xlogdefs.h's normal rules will prefer open_datasync, which (a) doesn't
- * perform better and (b) causes outright failures on ext4 data=journal
- * filesystems, because those don't support O_DIRECT.
