This patch (as1261) reduces the amount of detailed URB information logged by usbfs when the usbfs_snoop parameter is enabled. Currently we don't display the final status value for a completed URB. But we do display the entire data buffer twice: both before submission and after completion. The after-completion display doesn't limit itself to the actual_length value. But since usbmon is readily available in virtually all distributions, there's no reason for usbfs to print out any buffer contents at all! So this patch restricts the information to: userspace buffer pointer, endpoint number, type, and direction, length or actual_length, and timeout value or status. Now everything fits neatly into a single line. Along with those changes, the patch also fixes the snoop output for the REAPURBNDELAY and REAPURBNDELAY32 ioctls. The current version omits the 'N' from the names. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
