Initially I created the patch without adding prototypes but that patch was unreadable
Due to the common lines of code b/w the functions so created the prototypes to make the 
Patch more readable as suggested by Peter.

Will add one more patch in the next series to get rid of the prototypes.

Yes I agree l see that no comments for your series of patches as of now...
Let me know whether I should wait until your patches got applied or you want me to send the next version 
Of my patches...

Navakishore.
