[PATCH] firmware: fix BUG: in fw_realloc_buffer

2006-03-28T06:47:30+00:00

The fw_realloc_buffer routine does not handle an increase in buffer size of more than 4k. It's not clear to me why it expects that it will only get an extra 4k of data. The attached patch modifies fw_realloc_buffer to vmalloc as much memory as is requested, instead of what we previously had + 4k. I've tested this on my laptop, which would crash occaisionally on boot without the patch. With the patch, it hasn't crashed, but I can't be certain that this code path is exercised.

[PATCH] Unlinline a bunch of other functions

2006-01-15T02:27:06+00:00

Remove the "inline" keyword from a bunch of big functions in the kernel with the goal of shrinking it by 30kb to 40kb Signed-off-by: Arjan van de Ven Signed-off-by: Ingo Molnar Acked-by: Jeff Garzik Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] move capable() to capability.h

2006-01-12T02:42:13+00:00

- Move capable() from sched.h to capability.h; - Use where capable() is used (in include/, block/, ipc/, kernel/, a few drivers/, mm/, security/, & sound/; many more drivers/ to go) Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] driver core: replace "hotplug" by "uevent"

2006-01-05T00:18:08+00:00

Leave the overloaded "hotplug" word to susbsystems which are handling real devices. The driver core does not "plug" anything, it just exports the state to userspace and generates events. Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman

[PATCH] fix leaks in request_firmware_nowait

Wasn't checking return error and forgot to free in some case. Signed-off-by: Matthieu CASTET Cc: Greg KH Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] firmware: fix all kernel-doc warnings

2005-10-31T01:37:25+00:00

Convert existing function docs to kernel-doc format. Eliminate all kernel-doc warnings. Fix some doc typos and a little whitespace cleanup. Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] drivers/base/*: use kzalloc instead of kmalloc+memset

2005-09-13T15:22:27+00:00

Fixes a bunch of memset bugs too. Signed-off-by: Lion Vollnhals Signed-off-by: Jiri Slaby Cc: Greg KH Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] modified firmware_class.c to support no hotplug

2005-09-07T23:57:26+00:00

Upgrade the request_firmware_nowait function to not start the hotplug action on a firmware update. This patch is tested along with dell_rbu driver on i386 and x86-64 systems. Signed-off-by: Abhay Salunke Cc: Greg KH Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] request_firmware(): avoid race conditions

2005-06-29T04:20:30+00:00

Avoid race occurs when some process have open file descriptor for class device attributes and already firmware allocated memory are freed. Don't allow negative loading timeout. Signed-off-by: Stanislaw W. Gruszka Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Here we add a TIMEOUT value to the hotplug environment of the firmware requesting event. I will adapt udevd not to wait for anything else, if it finds a TIMEOUT key.
