USB: unkill cxacru atm driver

2007-08-22T21:27:58+00:00

it seems like you overdid it a bit in your quest to clean up the
use of urb->status. In this driver you read it the first thing, which
means that you are in a race against URB completion you'll
usually lose, returning -EINPROGRESS. This kills the driver.

that patch easier to review and apply in the future.

Freezer: make kernel threads nonfreezable by default

2007-07-17T17:23:02+00:00

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves.  This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.

It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.

The patch causes all kernel threads to be nonfreezable by default (ie.  to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE.  It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear.  Additionally, it updates documentation to
describe the freezing of tasks more accurately.

USB: cxacru: Cleanup sysfs attribute code

2007-07-12T23:29:45+00:00

This changes the format of unknown status values to be less verbose and
uses an array instead of several different snprintf calls. Since only
enum values are assigned to it, poll_state is changed from int to enum.
Use abs() for dB values instead of two almost identical return lines.

USB: cxacru: ignore error trying to start ADSL in atm_start

2007-06-08T23:24:31+00:00

The sysfs adsl_status attribute ignores (aside from returning -EIO to the
user) any error sending a START/STOP command to the device and there is at
least one firmware which never sends a response but appears to work
regardless.  Therefore atm_start should also continue if an error is received
so that such firmware is usable.

The official Conexant driver doesn't expect a reply either but this is for
another device (E2 router) and a commonly used firmware does respond.

Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing
ever checks for either of these values.

USB: cxacru: create sysfs attributes in atm_start instead of bind

2007-06-08T23:24:31+00:00

Since usbatm doesn't set the usb_interface driver data until after calling
bind and heavy_init, it would be NULL when the sysfs attributes are read.
Reading the MAC address from atm_dev before atm_dev exists would have been
be possible too.

Calling create_device_file in atm_start will avoid this problem, and the
data is useless until the first status poll runs.  However, it must be
ready before a status poll does a printk on line status change otherwise
userspace could react before the files exist.

For completeness I've moved remove_device_file to atm_stop so it's not
called in unbind when it's not needed.  There's no point starting ADSL if
atm_start could still fail either.
