--- Comment #2 from Eric van Gyzen <vangyzen at FreeBSD.org> ---
Those two syscalls were added between 11.0 and 11.1.  It sounds like you have
an 11.0 libc.  Try this:

$ objdump -T /lib/libc.so.7 | grep clock_nanosleep
00000000000e9a00 g    DF .text  0000000000000011  FBSDprivate_1.0
__sys_clock_nanosleep
000000000004cb10  w   DF .text  000000000000000e  FBSD_1.5    clock_nanosleep

$ objdump -T /lib/libc.so.7 | grep fdatasync
00000000000e99e0 g    DF .text  0000000000000011  FBSDprivate_1.0
__sys_fdatasync
00000000000e99e0  w   DF .text  0000000000000011  FBSDprivate_1.0 _fdatasync
000000000004ca20 g    DF .text  000000000000000b  FBSD_1.5    fdatasync

You should see output similar to the above.  If you see no output, you need to
get /lib/libc.so.7 from 11.1.  Of course, there may be many other files
out-of-sync, so you should take more complete measures to get your system into
a known-good state.
