From: Adrian Bunk <[email protected]> - unquoted
This patch contains the following possible cleanups:
- every function should #include the headers containing the prototypes
of it's global functions
- static functions in C files shouldn't be marked "inline", gcc should
know best when to inline them
- make needlessly global code static
- #if 0 the following unused global function:
- stale_inode.c: is_stale_inode()
Signed-off-by: Adrian Bunk <[email protected]>
[removed stale inode related fixes as stale_inode.c is gone]
