This patch was generated by the following semantic patch (a trimmed down
version of what is shipped with Linux sources):
@@
type T;
T[] E;
@@
(
- (sizeof(E)/sizeof(*E))
+ ARRAY_SIZE(E)
|
- (sizeof(E)/sizeof(E[...]))
+ ARRAY_SIZE(E)
|
- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)
)
The only manual adjustment was to include utils.h in misc/nstat.c to make
the macro known there.
