One could check if <linux/fiemap.h> is available, but that would add the dependency on kernel-headers being installed. Alternatively one could skip the test on non linux and linux < 2.6.27 But requiring ext4 is probably good enough to limit this to systems that actually do have fiemap available. Adding a comment about linux >= 2.6.27 might help us quickly eliminate false positives that are reported. cheers. Pádraig.
