+Subject: [PATCH] Reland "GCC: Fix base::internal::InvokeFuncImpl"
+
+This is a reland of 9293d5c86eec1c34fc00716645400b44a14e764e
+
+Original change's description:
+> GCC: Fix base::internal::InvokeFuncImpl
+> 
+> GCC doesn't like that the Value data member has no out-of-line
+> definition. The problem is triggered specifically only when compiling
+> 
+>   components/services/leveldb/leveldb_database_impl.cc
+> 
+> which has lambda functions returning locally-defined classes.
+> 
+> The current code works as-is in C++17 mode which introduces the concept
+> of inline variables, but in C++14 we need either an explicit out-of-line
+> definition or a function member instead of a data member.
+> 
+> Use std::integral_constant for defining the value.
+>

+Subject: [PATCH] [linux]: Remove linux namespace.
+
+'linux' turns out to be a prebuilt macro for GCC (not Clang)
+so using "namespace linux { ... }" actually does not compile.
+
+This CL fixes the issue by removing the namespace, and using
+Linux as a prefix for the corresponding class.
+
+Bug: 140419396
