Rather the second one, i.e. it fixes it for me. The patch is named sysfs-cache-the-last-sysfs_dirent-to-improve-readdir-scalability-v2.patch and is "stuck" in Greg's tree. Judging by the quilt series¹, the patch is slated for submission after 2.6.33. This late in the game for .32, I'm guessing maybe a stable backport after .33 is out?
