+Subject: [PATCH] Replace lseek64 with lseek
+
+meson defined _FILE_OFFSET_BITS=64 unconditionally, this implies that
+lseek and lseek64 are both same since they are using 64bit off_t,
+replacing lseek64 with lseek also helps in compiling with latest musl C
+library which has removed these from _GNU_SOURCE namespace unlike glibc
+where _GNU_SOURCE also implies _LARGEFILE64_SOURCE and the definition of
+lseek64 is still available.
