commit    f16735d80d2fbe1c86f4ac044ee66fe2073b8877
Author:   Thomas Munro <tmunro@postgresql.org>
Date:     Sun Feb 24 10:48:52 2019 +0000
First released in: 12.0, 9.4.22, 9.5.17, 9.6.13, 10.8, 11.3

    Tolerate EINVAL when calling fsync() on a directory.
    
    Previously, we tolerated EBADF as a way for the operating system to
    indicate that it doesn't support fsync() on a directory.  Tolerate
    EINVAL too, for older versions of Linux CIFS.
    
    Bug #15636.  Back-patch all the way.
