mm: implement per-zone shrinker
npiggin(a)suse.de writes: Allow the shrinker to do per-zone shrinking. This means it is called for each zone scanned.

Beyond the scope of this patch, but at some point this probably ne... 30 Jun 2010 10:52

fs: icache lazy lru
npiggin(a)suse.de writes: Impelemnt lazy inode lru similarly to dcache. This will reduce lock acquisition and will help to improve lock ordering subsequently. Or just drop inode LRU completely and only rely on the dcache for that? -Andi -- ak(a)linux.intel.com -- Speaking for myself only. -- To unsubsc... 1 Jul 2010 04:31

[PATCH] gainfar.c : skb_over_panic (kernel-2.6.32.15)
Fix possible skb_over_panic event in Freescale's "gianfar" driver. The skb_over_panic occurs due to calling skb_put() within gfar_clean_rx_ring(). This happens if (and only if) shortly prior to the event and a few lined above the skb_put(), an skb was queued back to the priv->rx_recycle queue due to RXBD_LAST... 24 Jun 2010 06:21

[PATCH 2/3] RTC/nuc900: patch for modifying enable/disable IRQs and driver data setting location
This patch does two modifications: (1) Adjust enable/disable IRQs location,enable it after rtc registration and disable it prior to unregistration. (2) Put 'platform_set_drvdata(pdev, nuc900_rtc)' in front of rtc registration still be safety, though there is no need to do this, when I move enable irq after rtc r... 24 Jun 2010 05:17
