Module Name:    src
Committed By:   gdt
Date:           Wed Mar 25 18:08:34 UTC 2020

Modified Files:
        src/lib/libc/sys: fdatasync.2
        src/sys/kern: vfs_syscalls.c

Log Message:
Relax fdatasync restriction that fd be writable

The restriction that a fd passed to fdatasync(2) must be writable was
added in 2003 in order to comply with POSIX.  Since then, POSIX has
removed that requirement, and POSIX-valid programs have been therefore
encountering errors on NetBSD.

Patch by Paul Ripke after discussion on netbsd-users.  Issue
discovered with pkgsrc/databases/mongodb3 as used by pkgsrc/net/unifi.
