According to chapter 14 of the coding style document:
"These generic allocation functions all emit a stack dump on failure when used
without __GFP_NOWARN so there is no use in emitting an additional failure
message when NULL is returned."

I think that these failures are not silent since __GFP_NOWARN is not
enabled.
