+Subject: [PATCH] src: fix compilation for glibc version 2.27.9000-36.fc29 and
+ newer
+
+As recent glibc versions (>= 2.27.9000-36.fc29) also define 'struct
+statx' which is also defined in linux/stat.h, compilation fails with
+error:
+
+| In file included from ../dt-utils-2018.05.0/src/crypto/digest.c:24:
+| [..]/usr/include/linux/stat.h:56:8: error: redefinition of 'struct statx_timestamp'

+|  struct statx
+|         ^~~~~
+
+The linux/stat.h originates from the code that was copied from barebox
+but is not explicitly required to be linux/stat.h instead of sys/stat.h
+and we do not actually use struct statx.
+
+Thus it is safe to simply replace occurrences of linux/stat.h by
+sys/stat.h to fix compilation.
