On some systems, __used is already defined in sys/cdefs.h and causes a build warning: scripts/mod/file2alias.c:85:1: warning: "__used" redefined In file included from /usr/include/stdio.h:64, from scripts/mod/modpost.h:1, from scripts/mod/file2alias.c:13: /usr/include/sys/cdefs.h:146:1: warning: this is the location of the previous definition This adds an extra check before defining the __used macro to see if the macro was already defined elsewhere.
