FYI: XFS has supported hole punching for more than 15 years, although
the first years obviously were't on Linux.
I was looking at the Windows API yesterday and you need
to check each volume for sparse support. So it is file
system dependent there as well: VFAT doesn't support
sparseness and NTFS (version ?) does.
From the perspective of user space tools, POSIX support
for sparseness would be helpful and FALLOC_FL_PUNCH_HOLE
looks like a step in that direction.
