Thu, 07 Jan 2021 10:46:51 +0000

open(2): Add O_DSYNC flag.POSIX O_DSYNC means that writes include an implicit fdatasync(2), justas O_SYNC implies fsync(2).VOP_WRITE() functions that understand the new IO_DATASYNC flag can actaccordingly, but we'll still pass down IO_SYNC so that file systems thatdon't understand it will continue to provide the stronger O_SYNCbehaviour.Flag also applies to fcntl(2).Reviewed by: kib, delphijDifferential Revision: https://reviews.freebsd.org/D25090 List of files: /freebsd-14.2/lib/libc/sys/open.2
