Yeah, I think that was missing in the original patch as well. Hope the

Returns a file's size on disk. Based on a patch by Chris Ball, improved
following suggestions by Chris Mason and Miao Xie.
Minimal example:
#include sys/ioctl.h
#include fcntl.h
#include stdint.h
#include stdio.h
#define BTRFS_IOCTL_MAGIC 0x94
#define BTRFS_IOC_COMPR_SIZE

Why don't you use btrfs_get_extent() to implement it?
Because I didn't know about it. :) Thanks, that simplifies things a lot.
