Pete Zaitcev ba6abf1352 [PATCH] USB: ub 1/3: Axboe's quasi-S/G ... This the quasi-S/G patch for ub as suggested by Jens Axboe at OLS and implemented that night before 4 a.m. Surprisingly, it worked right away... Alas, I had to skip some OLS partying, but it was for the good cause. Now the speed of ub is quite acceptable even on partitions with small block size. The ub does not really support S/G. Instead, it just tells the block layer that it does. Then, most of the time, the block layer merges requests and passes single-segmnent requests down to ub; everything works as before. Very rarely ub gets an unmerged S/G request. In such case, it issues several commands to the device. I added a small array of counters to monitor the merging (sg_stat). This may be dropped later.
