/* src/include/port/linux.h */ /* * 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. */ #define HAVE_LINUX_EIDRM_BUG /* * 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. */ #define PLATFORM_DEFAULT_SYNC_METHOD SYNC_METHOD_FDATASYNC
