I posted this before, but didn't see any discussion. This patch fixes a couple of places where the usb subsystem DMAs to/from local (stack) variables. This doesn't work on non-cache-coherent processors. I'm testing on PPC 4xx systems. Signed-off-by:

A few devices prefer not to have full-speed bandwidth reclamation turned on while they are being enumerated. In particular this seems to be true for the USB Bluetooth adapters built in to some laptop models (used for remote keyboards). This patch alters the UHCI driver so that control URBs for devices still in the USB_STATE_DEFAULT state will be placed on the low-speed queue rather than the full-speed queue. Since the low-speed queue isn't subject to bandwidth reclamation the devices will work properly. The negative impact on other devices is minimal; the process of device initialization will be slowed down by a few milliseconds. Signed-off-by:

In order for network device lifetime stuff to work properly, it is necessary for devices to allocate private data as part of alloc_etherdev. Also, netdev_priv() is improvement over dereferencing netdev->priv Signed-off-by:

Change other usb network driver to use alloc_etherdev to allocate the private data structure. And use netdev_priv to find it. Signed-off-by:

Basic HID driver support for USB suspend/resume. At least one keyboard works OK as a remote wakeup source ... unless you write the sysfs power/state attribute using that USB keyboard, in which case the input subsystem reports an endless stream of newlines! :) Someone still needs to implement some configurable timer to support the "suspend idle mice/keyboards/..." policy for devices that can issue wakeup events. In conjunction with autosuspend policies in hub and HCD (UHCI) code, that could allegedly save 2W of power by enabling the C3 state on Centrino laptops that use USB mice. Signed-off-by:

Some of the recent changes to change how descriptors are read have managed to confuse one USB keyboard. It recovers OK with a few retries though. Signed-off-by:

I have extended my driver to add support of the embedded USB port provided by some new Texas Instruments' handhelds. Things are the same except for the maximum packet size. Description: add support of the USB port embedded on some new TI handhelds (TI84+ and TI89 Titanium). Thanks, Romain. Signed-off-by:

the appended patch is not in yet, what gives? I sent it to Marcelo with an understanding that it would be in Linus tree any day now. It was a couple of months ago. It's not just BKL witchhunt either. I remember that it fixed an oops, although I do not remember the precise scenario by now (it had something to do with a race between ->release and ->disconnect).

This patch adds recognition/support for the PharosGPS puck, as included with Microsoft's Streets and Trips package. The device has an inline USB-to-serial converter which functions as a PL2303 but with different VENDOR_ID and PRODUCT_ID, and so the PL2303 driver is modified to recognize this additional device.

Following the recommendation of James Bottomley (of SCSI fame), this patch changes the queuecommand() routine so that when a command is received for a disconnected device, instead of accepting the command and then ignoring it, we fail the command immediately with DID_NO_CONNECT. This fixes a timeout-abort-oops sequence that would occur when the higher-level drivers (mostly the CD driver) try to queue a SYNCHRONIZE CACHE command during scsi_remove_host(). Signed-off-by:

The orphan list holds inodes that need to be truncated on recovery. In the O_DIRECT case, it's used if we extend the inode --- the truncate on recovery means we'll recover the newly-allocated disk blocks if we crash after the IO starts but before i_size is updated on disk. Now, the orphan list is *also* used to delete inodes that are unlinked but still-open. Those get truncated but also deleted on recovery. The orphan list is held both in memory and on disk. So the rules are that the inode can't be reclaimed while on the orphan list. There are only two cases --- either the inode is actively being written(O_DIRECT) or truncated (in which case the inode is by definition not going to be reused), or it's unlinked but still open (again, non-reclaimable). But in the case where you're truncating or write(O_DIRECT)ing a file that is *ALSO* unlinked, there's a problem --- the final unlink would put the inode on the orphan list, but the write/truncate would try to add/remove it. End result is that the inode disappears from the orphan list while it's still unlinked-but-in-use. That's just a leak-on-crash, it's not going to be detectable in normal use. But it's still a bug, and the way we fix it is for direct-IO and truncate not to do the ext3_orphan_del if the file is unlinked (ie. i_nlink==0). Signed-off-by:

The following patches provide an interface to the lease subsystem in the current VFS locking code. NFSv4 delegations and Samba op-locks share most architecture features. The version 4 NFS server delegation implementation should use leases to co-ordinate behavior between local, Samba, and NFS access. The main design points are - Seperate the fcntl interface from the file_lock FL_LEASE processing in fcntl_setlease, creating __setlease() called by fcntl_setlease() - Add new lock_manager callbacks to enable lease properties to be set, leases to be broken, and leases to be cleaned up: with default callbacks preserving the current fcntl_setlease properties. - Add a new interface, setlease() which also calls __setlease(), and remove_lease() for kernel lease managers (e.g. the v4 NFS server) This patch: Add a lock manager copy lock callback to locks_copy_lock() so that nfsd can set lease properties.

This patch adds a REISERFS_UNSUPPORTED_OPT flag to denote when a mount option is allowable, but is unsupported in the running configuration. This allows the potential for the set of mount options to be consistent, regardless of what features the kernel is compiled with. Rather than failing the mount, a warning is issued and the mount succeeds. Signed-off-by:
