FYI this broke CI on Alpine.

Alpine has problem with O_FSYNC:
In file included from ../include/tst_test.h:110,
from tst_fill_fs.c:13:
tst_fill_fs.c: In function 'fill_flat_vec':
tst_fill_fs.c:76:58: error: 'O_FSYNC' undeclared (first use in this function); did you mean 'O_ASYNC'?

It actually does not have it in fcntl.h (and nowhere in the sources).
Kind regards,
