The FIEMAP_EXTENT_SHARED flag was added into kernel since commit 8c0414cd524e, so undefined FIEMAP_EXTENT_SHARED resulted in complier error on old distros(e.g. RHEL6), as below: ---------------------------------------------------------------------- t_stripealign.c:99: error: 'FIEMAP_EXTENT_SHARED' undeclared (first use in this function) ---------------------------------------------------------------------- We fix it by defining the flag manually.
