An "ad Linus-em" counterexample:
"And if we have a Linux-specific magic system call or sync action, it's
going to be even more rarely used than fsync(). Do you think anybody
really uses the OS X FSYNC_FULL ioctl? Nope. Outside of a few databases,
it is almost certainly not going to be used, and fsync() will not be
reliable in general.
So rather than come up with new barriers that nobody will use, filesystem
people should aim to make "badly written" code "just work" unless people
are really really unlucky. Because like it or not, that's what 99% of all
code is."
