From 5f4e5752a8a3a72c79514def2ad9fc7cd410ce2e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 19 Sep 2016 10:12:45 +1000 Subject: fs: add iomap_file_dirty Originally-From: Christoph Hellwig This function uses the iomap infrastructure to re-write all pages in a given range. This is useful for doing a copy-up of COW ranges, and might be useful for scrubbing in the future.
