Now backing away slowly... Not sure what that means. The problem is trivial to reproduce. Killing these lines in shrink_list(): if (laptop_mode && !sc->may_writepage) goto keep_locked; makes it go away.

I'll poke at it some more. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
