+Subject: [PATCH] direct_mmap: Use off_t on linux
+
+off64_t is not provided without defining _LARGEFILE64_SOURCE on musl
+this define is not defined automatically like glibc where it gets
+defined when _GNU_SOURCE is defined. Using off_t makes it portable
+across musl/glibc and for using 64bit off_t on glibc 32bit systems
+-D_FILE_OFFSET_BITS=64 can be defined during build via CXXFLAGS
+
+Upstream-Status: Submitted [https://github.com/abseil/abseil-cpp/pull/1349]
