I used a coccinelle script:
* ran it with `make coccicheck MODE=patch SPFLAGS="--in-place --debug" COCCI=script.cocci`
* script:
```
virtual patch
@r1@
identifier ctl_table_name;
@@
static struct ctl_table ctl_table_name[] = {
...
-, {}
};
```
and a gawk script
* ran it with `for f in $(git grep -l "struct ctl_table") ; do script $f ; done`
* script:
```
#!/usr/bin/gawk -f
BEGINFILE {
RS=","
has_struct = 0
}
/(static )?(const )?struct ctl_table/ {
has_struct = 1
}
has_struct && /^(\n)?[\t ]*{(\n)*[\t ]*}/ {
print "Filename : " FILENAME ", Record Number : " FNR
}
```
At this point the coccinelle script gives me too many false positives
but the gawk is spot on. Thx for the sed one. Will make a note of it.
Best
