if this file is just a mirror from preferences in chrome, maybe the chrome
preferences should move down one layer so it can be used by both webview and
chrome. Why do we replicate it?

Also discounting the mirroring, the prefs are only used at the browser side, so
probably this file should not be in common.

They should get moved in https://codereview.chromium.org/1414313002/. I will
remove this file when we update webview to use the dynamic policies. Will move
to browser for now

ok

In the end this won't move to //net. Moved them in browser_context.h

+namespace prefs {
+
+// Used for Kerberos authentication
+extern const char kAuthAndroidNegotiateAccountType[];

creating this file only for two const char * seems unnecessary. Are you
expecting to add more pref names in future?

[dgn, 2015/11/13 12:37:08]

Depends on whether we need to support more policies for which preferences are
defined in the //chrome layer. I personally don't have any plans about that for
now.
