Andy Shevchenko a93917d39f USB: gadget: storage: optional SCSI WRITE FUA bit ... MS Windows mounts removable storage in "Removal optimized mode" by default. All the writes to the media are synchronous which is achieved by setting FUA (Force Unit Access) bit in SCSI WRITE(10,12) commands. This prevents I/O requests aggregation in block layer dramatically decreasing performance. This patch brings an option to accept or ignore mentioned bit a) via specifying module parameter "nofua", or b) through sysfs entry /sys/devices/platform/_UDC_/gadget/gadget-lunX/nofua (_UDC_ is the name of the USB Device Controller driver) Patch is based on the work that was done by Denis Karpov for Maemo 5 platform.
