USB: remove short initial timeout for device descriptor fetch

2008-07-19T19:46:12+00:00

This patch (as905) removes a micro-optimization from the hub port initialization code. Previously we had been using a short timeout on the first attempt the read the device descriptor; now we will use the standard timeout length. It's not clear that the short timeout ever provided any benefit. And now we know of one case where it actually hurts: The device can't meet the short timeout and then it gets terminally confused. This fixes Bugzilla #8444. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman Signed-off-by: Adrian Bunk

[PATCH] USB: usbcore: usb_set_configuration oops (NULL ptr dereference)

2006-04-07T16:44:27+00:00

When trying to deconfigure a device via usb_set_configuration(dev, 0), 2.6.16-rc kernels after 55c527187c9d78f840b284d596a0b298bc1493af oops with "Unable to handle NULL pointer dereference at...". This is due to an unchecked dereference of cp in the power budget part. This patch was already included in Linus' tree.

[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem

2006-01-09T23:59:24+00:00

This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different. Modified-by: Ingo Molnar (finished the conversion) Signed-off-by: Jes Sorensen Signed-off-by: Ingo Molnar

[PATCH] shrink dentry struct

2006-01-09T04:13:58+00:00

Some long time ago, dentry struct was carefully tuned so that on 32 bits UP, sizeof(struct dentry) was exactly 128, ie a power of 2, and a multiple of memory cache lines. Then RCU was added and dentry struct enlarged by two pointers, with nice results for SMP, but not so good on UP, because breaking the above tuning (128 + 8 = 136 bytes) This patch reverts this unwanted side effect, by using an union (d_u), where d_rcu and d_child are placed so that these two fields can share their memory needs. At the time d_free() is called (and d_rcu is really used), d_child is known to be empty and not touched by the dentry freeing. Lockless lookups only access d_name, d_parent, d_lock, d_op, d_flags (so the previous content of d_child is not needed if said dentry was unhashed but still accessed by a CPU because of RCU constraints) As dentry cache easily contains millions of entries, a size reduction is worth the extra complexity of the ugly C union.

[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
