include/linux/tracepoint.h:141:5: warning: `isolated' may be used uninitialized in this function [-Wmaybe-uninitialized]
((void(*)(proto))(it_func))(args); \
^
mm/huge_memory.c:2327:6: note: `isolated' was declared here
int isolated, result = 0;
We make use of isolated in error path before it get initialized.
