The patch titled seq_file: fix big-enough lseek() + read() has been removed from the -mm tree. Its filename was seq_file-fix-big-enough-lseek-read.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: seq_file: fix big-enough lseek() + read() From: Alexey Dobriyan <adobriyan@xxxxxxxxx> 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 ("seq_file: more atomicity in traverse()").
