Description Michael 2017-02-07 06:10:09 UTC 
In cl_page_ALLOC:
	else {
--->     page = ERR_PTR(-ENOMEM);
    }
    return page;

	The return value in cl_page_alloc can be ERR_PTR(-ENOMEM), which is then returned in cl_page_find.  Is this error handled in the caller function? Why is a page used for returning the -ENOMEM error?
