+From 10e2247f7b4692e80d185bb65ea641585bdc6b4d Mon Sep 17 00:00:00 2001

+Subject: [PATCH] misc: rename copy_file_range to copy_file_chunk
+
+As of 2.27, glibc will have a copy_file_range library call to wrap the
+new copy_file_range system call.  This conflicts with the function in
+misc/create_inode.c, which this patch renames _copy_file_range.
