2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Alexey Dobriyan commit f01d1d546abb2f4028b5299092f529eefb01253a upstream. lseek() further than length of the file will leave stale ->index (second-to-last during iteration). Next seq_read() will not notice that ->f_pos is big enough to return 0, but will print last item as if ->f_pos is pointing to it. Introduced in commit cb510b8172602a66467f3551b4be1911f5a7c8c2 aka "seq_file: more atomicity in traverse()".
