Today, some calls to abort() do not have a preceding error string that might hint to the end user why QEMU died. Debugging such scenarios is painful today.
This patchset attempts to clean up some dead code in vvfat.c; it also aims to improve qemu error-reporting by placing error messages that precede calls to abort(). Prerna Saxena (2): Block: Cleanup vvfat.c to remove dead code.
