* Merge branch 'bkl-removal' of git://git.lwn.net/linux-2.6Linus Torvalds2009-03-261-1/+6
|\ | | | | | | | | | | | | | | * 'bkl-removal' of git://git.lwn.net/linux-2.6: Rationalize fasync return values Move FASYNC bit handling to f_op->fasync() Use f_lock to protect f_flags Rename struct file->f_ep_lock
| * Use f_lock to protect f_flagsJonathan Corbet2009-03-161-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | Traditionally, changes to struct file->f_flags have been done under BKL protection, or with no protection at all. This patch causes all f_flags changes after file open/creation time to be done under protection of f_lock. This allows the removal of some BKL usage and fixes a number of longstanding (if microscopic) races.

This ensures that both configurations can pass the USBCV remote wakeup tests when the OTG test mode is enabled. This changes behavior by adding autoresume support to the loopback config even in non-OTG mode; the test failure was that it didn't work in OTG mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is really a follow up to the modifications Alan Cox made for commit 95da310e66ee8090119596c70ca8432e57f9a97f to pass a tty_struct to various interface functions, which broke the serial configuration (termios) functions when the device is being used as a console. These changes restore the configuration to proper functioning both as a tty and as a console.

Currently we call usb_set_interface() for every interface in the active configuration; this is to put the interface into the same altsetting as before the reset and to make sure that the host's endpoint state matches the device's endpoint state. However, sending a Set-Interface request is a waste of time if an interface was already in altsetting 0 before the reset, since it is certainly in altsetting 0 afterward. In addition, many devices can't handle Set-Interface requests -- they crash when they receive them. So instead, the patch adds code to check each interface. If the interface wasn't in altsetting 0 before the reset, we go head with the Set-Interface request as before. But if it was then we skip sending the Set-Interface request, and we clear out the host-side endpoint state by calling usb_disable_interface() followed by usb_enable_interface(). The patch also adds a couple of new comments to explain what's going on. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The /dev/ttyUSB0 is not released until being closed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is no longer usable by minicom. It is really a mess for a minicom user.

This is correct for OTG hosts, where either SRP or an ID interrupt could turn VBUS on again. However, for non-OTG hosts there's no way to turn VBUS on again, so the host becomes unusable. And the procfs entry which once allowed a manual workaround for this is now gone. This patch adds an is_otg_enabled() check before scheduling the switch-off timer in disconnect path, supporting a "classic host" mode where SRP is unavailable.

This scheme doesn't work for devices which are connected to a high to full speed tree (transaction translator) as there is no NAK timeout interrupt from the musb controller from such devices.

| | * | USB: musb: rewrite host periodic endpoint allocationSergei Shtylyov2009-03-242-18/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current MUSB host code doesn't make use of all the available FIFOs in for periodic transfers since it wrongly assumes the RX and TX sides of any given hw_ep always share one FIFO. Change: use 'in_qh' and 'out_qh' fields of the 'struct musb_hw_ep' to check the endpoint's business; get rid of the now-unused 'periodic' array in the 'struct musb'. Also optimize a loop induction variable in the endpoint lookup code.
