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.
