[Xen-devel] [PATCH] today's gcc4ism

[Rik van Riel <riel@xxxxxxxxxx>]

New from yesterday night's snapshot.  I'm not 100% sure, but it
looks like __gnttab_map_grant_ref() might indeed return 0 without
initialising va ...

grant_table.c: In function 'do_grant_table_op':
grant_table.c:348: warning: 'va' may be used uninitialized in this function
make[3]: *** [grant_table.o] Error 1
