Subject: [PATCH 8/9] fscanner: swallow function as parameters

Some functions take as a parameter a pointer to another function. This
|
|
|
565b65 |
causes troubles in the cscope scanner and such function definition is
|
|
|
565b65 |
dropped on the floor.
|
|
|
565b65 |
|
|
|
565b65 |
Instead of choking and skipping the definition/declaration, teach the
|
|
|
565b65 |
scanner about this case. So now cscope will not skip those and put
|
|
|
565b65 |
them properly in the index.
|
|
|
565b65 |
|
|
|
565b65 |
I carry this patch for a couple of months and using cscope daily on
|
|
|
565b65 |
the Linux kernel and see no problems.
