+Subject: [PATCH] Replace statfs64 with statfs
+
+autoconf AC_SYS_LARGEFILE is used by configure to add needed defines
+when needed for enabling 64bit off_t, therefore replacing statfs64 with
+statfs should be functionally same. Additionally this helps compiling
+with latest musl where 64bit LFS functions like statfs64 and friends are
+now moved under _LARGEFILE64_SOURCE feature test macro, this works on
+glibc systems because _GNU_SOURCE macros also enables
+_LARGEFILE64_SOURCE indirectly. This is not case with musl and this
+latest issue is exposed.
+
