Kyle Evans	142c5c8c36	memfd_create(3): Don't actually force hugetlb size with MFD_HUGETLB ... The size flags are only required to select a size on systems that support multiple sizes. MFD_HUGETLB by itself is valid.	2019-09-29 17:30:10 +00:00

Kyle Evans	a9ac5e1424	sysent: regenerate after r352705 ... This also implements it, fixes kdump, and removes no longer needed bits from lib/libc/sys/shm_open.c for the interim.	2019-09-25 18:09:19 +00:00
Kyle Evans	3e25d1fb61	Add linux-compatible memfd_create ... memfd_create is effectively a SHM_ANON shm_open(2) mapping with optional CLOEXEC and file sealing support. This is used by some mesa parts, some linux libs, and qemu can also take advantage of it and uses the sealing to prevent resizing the region. This reimplements shm_open in terms of shm_open2(2) at the same time. shm_open(2) will be moved to COMPAT12 shortly.
