Hi all, This series enhances the e2fsprogs build system to allow us to take advantage of new compiler technologies. The first patch enables LTO, which can perform executable-wide code optimizations (particularly eliminating dead functions). The three patches after that enable the sanitizers for undefined behavior, memory access, and thread safety. With these sanitizers we can collect runtime reports about questionable C code, memory access problems, and thread safety problems (though at the moment e2fsprogs isn't heavily threaded). Questions? Comments? This series targets e2fsprogs 1.45. --D
