2nd try
initial
Make _get_sock_addr return correct address in kernel before 2.6.16.
Automatically print written but unread globals
Make nodwf test passed when CONFIG_QUOTACTL unset
Uses STAPCONF_DPATH_PATH instead of a kernel version check.
Simplified "rpm" target a bit.
Moved tar archive creation step from "rpm" target to "dist-gzip" target.
