Good morning! Linux has fallocate(fd, FALLOC_FL_PUNCH_HOLE|FALLOC_FL_KEEP_SIZE, ...) to punch a hole into a file, i.e. deallocate the blocks given and make the file a "sparse file". But how is this implemented on NFSv4.2 COMPOUND level? How does a NFSv4 compound look like to punch a hole say from position 30000 to position 35721?
