Feature #8671: support SEEK_DATA and SEEK_HOLE

• Status: Closed
• Assignee: Glass_saga (Masaki Matsushita)
• Target version: 2.1.0

[Glass_saga (Masaki Matsushita)]

SEEK_DATA and SEEK_HOLE are whences for lseek(2) supported by Linux since version 3.1.
These are useful to deal with sparse files.
I propose that ruby supports these whences.
