From 6a177381007b463ad611375cce526c24f12ab081 Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Fri, 28 Feb 2020 13:04:17 +0000 Subject: Btrfs: move all reflink implementation code into its own file The reflink code is quite large and has been living in ioctl.c since ever. It has grown over the years after many bug fixes and improvements, and since I'm planning on making some further improvements on it, it's time to get it better organized by moving into its own file, reflink.c (similar to what xfs does for example). This change only moves the code out of ioctl.c into the new file, it doesn't do any other change.
