Subject: [PATCH 1/1] fscanner: swallow function as parameters
|
|
MIME-Version: 1.0
|

Content-Type: text/plain; charset=UTF-8

|
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.
