Subject: [PATCH 8/9] fscanner: swallow function as parameters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some functions take as a parameter a pointer to another function. This
causes troubles in the cscope scanner and such function definition is
dropped on the floor.

Instead of choking and skipping the definition/declaration, teach the
scanner about this case. So now cscope will not skip those and put
them properly in the index.

I carry this patch for a couple of months and using cscope daily on
the Linux kernel and see no problems.
