The change looks good. I have two comments:

http://codereview.chromium.org/146136/diff/1/5
File chrome/browser/net/chrome_url_request_context.h (right):

http://codereview.chromium.org/146136/diff/1/5#newcode33
Line 33: const FilePath& disk_cache_path, int max_size);
given that this function has no explanation what the parameters are , I feel
that the max_size is misleading. One could read it as the maxium size of the
RequestContext. I am ok with no comments but the name imho should be like
cache_max_size or something like that. Same for the other instances of max_size
here.

http://codereview.chromium.org/146136/diff/1/3
File chrome/browser/profile.cc (right):

http://codereview.chromium.org/146136/diff/1/3#newcode763
Line 763: max_size = 0;
being the same code in both functions it would be nice if they are factored in a
local function
