This mirrors the functionality that driver_for_each_device has as well.
We add a start variable, and all callers of the function are fixed up at
the same time.The block layer will be using this new functionality in a follow-on
patch.Cc: Kay Sievers

Now that device_create() has been audited, rename things back to the
original call to be sane.Keep the device_create_drvdata macro around to make merges easier.

There are no more users of this, and it is racy. Use
device_create_drvdata() or device_create_vargs() instead.Signed-off-by: Greg Kroah-Hartman

Switch over to use the shiny new device_create_drvdata() call
instead of the original device_create() calls, so this continues
to work after device_create() is removed.Note that this driver never had the race which motivated removing
the original call; it locked correctly.Signed-off-by: David Brownell

Some (block) devices have a '/' in the name, and need special
handling. Let's have that rule to the core, so we can remove it
from the block class.Signed-off-by: Kay Sievers
Signed-off-by: Greg Kroah-Hartman -
Why?:
There are occasions where userspace would like to access sysfs
attributes for a device but it may not know how sysfs has named the
device or the path. For example what is the sysfs path for
/dev/disk/by-id/ata-ST3160827AS_5MT004CK? With this change a call to
stat(2) returns the major:minor then userspace can see that
/sys/dev/block/8:32 links to /sys/block/sdc.What are the alternatives?:
1/ Add an ioctl to return the path: Doable, but sysfs is meant to reduce
the need to proliferate ioctl interfaces into the kernel, so this
seems counter productive.2/ Use udev to create these symlinks: Also doable, but it adds a
udev dependency to utilities that might be running in a limited
environment like an initramfs.3/ Do a full-tree search of sysfs.

This patch (as1110) reverts an earlier patch meant to help with
Wireless USB host controllers. These controllers can have bulk
maxpacket values larger than 512, which puts unusual constraints on
the sizes of scatter-gather list elements. However it turns out that
the block layer does not provide the support we need to enforce these
constraints; merely changing the DMA alignment mask doesn't help.
Hence there's no reason to keep the original patch. The Wireless USB
problem will have to be solved a different way.In addition, there is a reason to get rid of the earlier patch. By
dereferencing a pointer stored in the ep_in array of struct
usb_device, the current code risks an invalid memory access when it
runs concurrently with device removal. The members of that array are
cleared before the driver's disconnect method is called, so it should
not try to use them.Signed-off-by: Alan Stern

This patch (as1109b) makes USB-Persist more resilient to errors. With
the current code, if a normal resume fails, it's an unrecoverable
error. With the patch, if a normal resume fails (and if the device is
enabled for USB-Persist) then a reset-resume is tried.This fixes the problem reported in Bugzilla #10977.
