+Subject: [PATCH] executor: Include missing linux/falloc.h
+
+Its needed for FALLOC_FL_ZERO_RANGE which needs this header, it works
+with glibc because fcntl.h includes this header indirectly, however the
+failure comes to fore with musl C library where this header is not
+included indirectly by other system headers, therefore include it as
+required.
+
+Fixes
+In file included from executor/common.h:505:
+executor/common_linux.h:5604:16: error: use of undeclared identifier 'FALLOC_FL_ZERO_RANGE'
+        fallocate(fd, FALLOC_FL_ZERO_RANGE, 0, SWAP_FILE_SIZE);
+                      ^
