On occasions diff output does not render the same as it does when
editing a file. For example, while removing checkpatch tab warning
the following diff was generated
-#define KS_WLAN_SET_WPS_ENABLE SIOCIWFIRSTPRIV + 4
-#define KS_WLAN_GET_WPS_ENABLE SIOCIWFIRSTPRIV + 5
+#define KS_WLAN_SET_WPS_ENABLE SIOCIWFIRSTPRIV + 4
+#define KS_WLAN_GET_WPS_ENABLE SIOCIWFIRSTPRIV + 5
However when editing the file the alignment was not changed, just tabs
were inserted instead of spaces.
I had the same thing happen a few days ago (reproduced here from
memory)
-static void foo(struct bar *barp, struct baz *bazp)
+static void foo(struct bar *barp,
+ struct baz *bazp)
{
...
When editing the file the two s's in struct were aligned but not in
the diff output. I reapplied this patch to a clean tree and it applied
correctly.
How do maintainers visually parse this if the output is not identical in the
diff and the file once applied?
thanks,
Tobin.
