2006-10-01[PATCH] leds: turn LED off when changing triggersPaul Collins
I was playing with LED triggers when I noticed that changing from heartbeat (or ide-disk) to "none" at the right moment would leave the LED stuck on. This is easy to reproduce by doing "find / >/dev/null" with the ide-disk trigger enabled and then switching to "none". Here is a patch that fixes the problem by explicitly turning the LED off after removing the existing trigger.

2006-07-10[PATCH] LED Class support for Soekris net48xxChris Boot
Add LED Class device support for the Soekris net48xx Error LED. Tested only on a net4801, but should work on a net4826 as well. I'd love to find a way of detecting a Soekris net48xx device but there is no DMI or any Soekris-specific PCI devices.

2006-06-27[PATCH] spin/rwlock init cleanupsIngo Molnar
locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
