[patch] gpio: potential null dereference
Smatch found a potential null dereference in gpio_setup_irq(). The "pdesc" variable is allocated with idr_find() that can return NULL. If gpio_setup_irq() is called with 0 as gpio_flags and "pdesc" is null, it would OOPs here. Signed-off-by: Dan Carpenter <error27(a)gmail.com> diff --git a/drivers/gpio/gpioli... 26 Apr 2010 16:04

xattr: define vfs_getxattr_alloc and vfs_xattr_cmp
Quoting Mimi Zohar (zohar(a)linux.vnet.ibm.com): vfs_getxattr_alloc() and vfs_xattr_cmp() are two new kernel xattr helper functions. vfs_getxattr_alloc() first allocates memory for the requested xattr and then retrieves it. vfs_xattr_cmp() compares a given value with the contents of an extended attribute. ... 26 Apr 2010 16:04

[PATCH] ftrace: print sample std dev when function profiling
When combined with function graph tracing the ftrace function profiler also prints the average run time of functions. While this gives us some good information, it doesn't tell us anything about the variance of the run times of the function. This change prints out the s^2 sample standard deviation alongside the ave... 26 Apr 2010 14:55

[PATCH 1/4] Minimal support for viafb suspend/resume
From: Deepak Saxena <dsaxena(a)laptop.org> This patch adds minimal support for suspend/resume of the VIA framebuffer device. It requires a version of OFW that restores the video mode. This patch is OLPC-specific as the proper upstream solution is to move the VIA video path to using the kernel modesetting infras... 26 Apr 2010 14:55
