Looks for a specific file in the patch called drivers/net

silent

Yes

No match, the script counts slashes

+sub file_match_pattern {
+    my ($file, $pattern) = @_;
+    if (substr($pattern, -1) eq "/") {
+       if ($file =~ m@^$pattern@) {
+           return 1;
+       }
+    } else {
+       if ($file =~ m@^$pattern@) {
+           my $s1 = ($file =~ tr@/@@);
+           my $s2 = ($pattern =~ tr@/@@);
+           if ($s1 == $s2) {
+               return 1;
+           }
+       }
+    }
+    return 0;
+}

Enhancements appreciated.
