+Subject: [PATCH] compat: Define off64_t as off_t on linux
+
+This helps compile with latest musl, where off64_t is not defined
+unless _LARGEFILE64_SOURCE is defined, on glibc _LARGEFILE64_SOURCE is
+defined if _GNU_SOURCE is defined, so the problem is only seen with musl
+
+Upstream-Status: Submitted [https://github.com/lttng/lttng-tools/pull/164]
