This is a cool program, but programmers were asking (and answering)
this same question 20+ years ago before

See star .

Mike, I was hoping that some one has a complete example for a bool
has_file_one_or_more_holes(const char *path) function.

How can I test if a file on ZFS has holes, i.e. is a sparse file,

I see nothing unusual in the lockstat data. I think you're barking up
the wrong tree.

VMFS-5 block size is 1Mb. Not sure how it corresponds with ZFS.
Setup details follow:
- 11 pairs of mirrors;
- 600Gb 15k SAS disks;
- SSDs for L2ARC and ZIL
