btrfs: remove unused function prototypes
I wrote the following coccinelle script to find function declarations
that didn't have the corresponding code for them
@funcproto@
identifier func;
type T;
position p0;
@@
T func@p0(...);
@funccode@
identifier funcproto.func;
position p1;
@@
func@p1(...) { ... }
@script:python depends on !funccode@
p0 << funcproto.p0;
@@
print("Proto with no function at %s:%s" % (p0[0].file, p0[0].line))
and ran it against btrfs, which identified the 4 function prototypes
I've removed in this patch.
