Particulary interesting commits: Please see this posting, which also contains a pointer to the necessary patch: http://lkml.indiana.edu/hypermail/linux/kernel/0812.1/02305.html According to GregKH it will be in -stable.10, but in the meantime you can also apply the patch from http://tinyurl.com/5gpqkj on top stable .8 (which introduced the regression) or .9. At this point it is not clear whether the changes to inotify caused this or just fell victim to the parallel regression in idr. -h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
