+Subject: [PATCH] Support data types larger than 128 bytes
+
+Recent versions of systemd (starting with v238) started to check for the
+existence of the statx structure using the cc.sizeof() operation. The cc
+compiler implementation fails to detect this structure because it's size
+limit is 128, meaning it will fail for any type larger than 128 bytes in
+the following way during cross-compilation checks:
+
+        meson.build:10:2: ERROR: Cross-compile check overflowed
+
+Increase the size limit for data types to 1024 bytes, which should give
+plenty of room for even large data structures. This is obviously not
+guaranteed to be an upper bound, but given the binary search algorithm
+implemented in the cross-compile check, raising the limit too high may
+significantly increase the time required for this check on smaller data
+types.
