From a133d952b44cef278d2da664d742d51ef95f4dd3 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 12 Aug 2013 20:49:48 +1000 Subject: xfs: consolidate extent swap code So we don't need xfs_dfrag.h in userspace anymore, move the extent swap ioctl structure definition to xfs_fs.h where most of the other ioctl structure definitions are. Now that we don't need separate files for extent swapping, separate the basic file descriptor checking code to xfs_ioctl.c, and the code that does the extent swap operation to xfs_bmap_util.c. This cleanly separates the user interface code from the physical mechanism used to do the extent swap.
