Subject: [PATCH 1/2] cifs: remove some camelCase and also some static build
warnings
Remove warnings for five global variables. For example:
fs/cifs/cifsglob.h:1984:24: warning: symbol 'midCount' was not declared. Should it be static?
Also change them from camelCase (e.g. "midCount" to "mid_count")
