[PATCH] touchscreen: ads7846: please don't touch free'd memory
If the _probe() method fails, the 'ts' struct is freed, yet it is still used as the drvdata passed to suspend/resume/remove methods. Even though the input device does not get registerd, the driver's suspend/resume methods still get called as it's a registered SPI device. This patch adds sanity checks to these meth... 18 May 2010 20:20

[PATCH 2/2] tmpfs: Make tmpfs scalable with caches for free blocks
The current implementation of tmpfs is not scalable. The stat_lock is contended whenever we need to get a new page, leading to lots of lock contentions. This patch makes use of the qtoken library to maintain local caches of free pages to speed up getting and returning of pages without acquisition of stat_lock.... 18 May 2010 20:20

[PATCH 0/2] tmpfs: Improve tmpfs scalability
We created a token jar library implementing per cpu cache of tokens to avoid lock contentions whenever we retrieve or return a token to a token jar. Using this library with tmpfs, we find Aim7 fserver throughput improved 270% on a 4 socket, 32 cores NHM-EX system. In current implementation of tmpfs, whenever... 18 May 2010 20:20
