The patch titled swapfile: let others seed random has been removed from the -mm tree. Its filename was swapfile-let-others-seed-random.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: swapfile: let others seed random From: Hugh Dickins <hugh@xxxxxxxxxxx> Remove the srandom32((u32)get_seconds()) from non-rotational swapon: there's been a coincidental discussion of earlier randomization, assume that goes ahead, let swapon be a client rather than stirring for itself.
