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:

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. Signed-off-by:

A couple of USB register initializations had to be changed on MPC85xx platforms. This is due to the internal SoC buses being different on MPC83xx SoCs vs MPC85xx SoCs. We currently handle this via an ifdef since 83xx and 85xx are mutually exclusive kernel builds. Signed-off-by:

Fix pointer/int cast in USB devio code, and thus avoid a compiler warning. A void* data argument passed to bus_find_device() and thence to match_devt() is used to carry a 32-bit datum. However, casting directly between a u32 and a pointer is not permitted - there must be an intermediate cast via (unsigned) long. This was introduced by the following patch: commit 94b1c9fa060ece2c8f080583beb6cc6008e41413 Author: Alan Stern <stern@rowland.harvard.edu> Date: Tue Jun 24 14:47:12 2008 -0400 usbfs: simplify the lookup-by-minor routines This patch (as1105) simplifies the lookup-by-minor-number code in usbfs. Instead of passing the minor number to the callback, which must then reconstruct the entire dev_t value, the patch passes the dev_t value directly. Signed-off-by:

This patch (as1107) fixes a small bug in the usbfs registration and unregistration code. It avoids leaving an error value stored in the device's usb_classdev field and it avoids trying to unregister a NULL pointer. (It also fixes a rather extreme overuse of whitespace.) Signed-off-by:
