We already have ioctl(DIOCGDELETE) for that. newfs(8) uses it.

Correct. TRIM is both the catch-all term people use, as well as the name of
a specific DSM (data set management) command in

Hole-punching has been discussed on these lists before[1]. It basically
means to turn a dense file into a sparse file by deallocating storage for
