So my current suggestion on this is to understand why __reclaim_stacks is not starting with a lll_unlock before the list_for_each runs, I'll look into this next week if nobody explained it yet ;). Statistically speaking it's more likely to be the kernel patch to be buggy and this is likely a faulty theory I know, but it's not impossible that this is an unrelated bug that was hidden as it required userland list_del/add/splice to race against the kernel ptep_set_wrprotect single instruction. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
