Recent udev versions probe loop devices for filesystems meaning that the /dev/disk hierarchy may contain useful entries such as $ ls -l /dev/disk/by-label/Fedora-12-x86_64-Live lrwxrwxrwx 1 root root 11 Mar 11 13:41 /dev/disk/by-label/Fedora-12-x86_64-Live -> ../../loop0 Unfortunately, no "change" uevent is generated when the loop device is detached so the symlink persists. Additionally, no "change" uevent is guaranteed to be generated when attaching an fd or changing capacity. For example, user space could open the loop device O_RDONLY (in fact, recent util-linux-ng does this) so udev's OPTIONS+="watch" machinery may not trigger the "change" uevent. This patch ensures that the "change" uevent is generated in all of these cases. As a result, the /dev/disk hierarchy works as expected for loop devices.

While device_shutdown() walks through devices_kset to shutdown all devices, device unplug events may race to shutdown individual devices. Specifically, sd_shutdown(), on behalf of fc_starget_delete(), has been observed deleting devices during device_shutdown()'s list traversal. So we factor out list_for_each_entry_safe_reverse(...) in favor of while (!list_empty(...)). Signed-off-by: NHugh Daschbach <hdasch@broadcom.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

When we use request_firmware_nowait(), userspace may not want to answer negatively right away when for example it is answering from an initrd only, but with request_firmware() it has to in order to not delay the kernel boot until the request times out. This allows userspace to differentiate between the two in order to be able to reply negatively to async requests only when all filesystems have been mounted and have been checked for the requested firmware file.

The conversion of device->sem to device->mutex resulted in lockdep warnings. Create a novalidate class for now until the driver folks come up with separate classes. That way we have at least the basic mutex debugging coverage. Add a checkpatch error so the usage is reserved for device->mutex.

When runtime PM for platform_bus was added, it allowed for platforms to customize the runtime PM methods since they are defined as weak symbols. This patch allows platforms to also extend the system PM methods with custom hooks so runtime PM and system PM extensions can be managed together by custom platform-specific code.

This patch (as1351) removes an unnecessary and unwanted assignment from device_initialize(). The wakeup flags are set to 0 along with everything else when the device structure is allocated, so we don't need to do it again. Furthermore, the subsystem might already have set these flags to their correct values; we don't want to override it.

This patch fix a potential race condition in the driver_bound() function in the file driver/base/dd.c. The broadcast of the BUS_NOTIFY_BOUND_DRIVER notifier should be done after adding the new device to the driver list. Otherwise notifier listener will fail if they use functions like usb_find_interface(). The patch is against kernel 2.6.33. Please merge it.

fix memory leak introduced by the patch 6e03a201: firmware: speed up request_firmware() 1. vfree won't release pages there were allocated explicitly and mapped using vmap. The memory has to be vunmap-ed and the pages needs to be freed explicitly 2. page array is moved into the 'struct firmware' so that we can free it from release_firmware() and not only in fw_dev_release() The fix doesn't break the firmware load speed.

Right now quirks are printed only when the are manually overriden with the module parameters.

Increase the bulk-out buffer size to avoid any regression in throughput after replacing the old writing scheme which used dynamic buffers (e.g. up to 2k). 256b has been determined to be a good choice for several drivers including ftdi_sio which used to have a more or less identical write implementation.
