[PATCH 19/49] xfs: split out inode log item format definition

Dave Chinner
2013-07-19T06:45:49Z

From: Dave Chinner <dchinner@redhat.com>

The EFI/EFD item format definitions are shared with userspace. Split
the out of header files that contain kernel only defintions to make
it simple to shared them.
