Alan Stern fca94748c5 USB: usbmon: fix bug in mon_buff_area_shrink ... This patch (as1299b) fixes a bug in an error-handling path of usbmon's binary interface. The storage area for URB data is divided into fixed-size blocks. If an URB's data can't be copied, the area reserved for it should be decreased to the size of the truncated information (rounded up to a block boundary). Rounding up the amount to be removed and subtracting it from the reserved size is definitely the wrong thing to do. Also, when the data for an isochronous URB can't be copied, we can still copy the isoc packet descriptors. In fact the current code does copy the descriptors, but then sets the capture length to 0 so they remain inaccessible. The capture length should be reduced to the length of the descriptors, not set to 0.
