[PATCH] KVM: deprecate KVM_WERROR in favor of general WERROR

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Setting WERROR for random subsystems make life really hard
for subsystems which want to build-test their stuff with W=1.
WERROR for the entire kernel now exists and can be used
instead. W=1 people probably know how to deal with the global
W=1 already, tracking all per-subsystem WERRORs is too much...

 -------
 At a bare minimum, *all* patches in a series must build cleanly for KVM_INTEL=m
-KVM_AMD=m, and KVM_WERROR=y.  Building every possible combination of Kconfigs
+KVM_AMD=m, and WERROR=y.  Building every possible combination of Kconfigs
 isn't feasible, but the more the merrier.  KVM_SMM, KVM_XEN, PROVE_LOCKING, and
 X86_64 are particularly interesting knobs to turn.
