Dmitry, Please find enclosed the third version of the evdev buffer patches. This version has one more patch; the locking mechanism has been broken out into its own file, buflock.h, adding a fair amount of documentation. The mechanism has been moderately tested, showing graceful dropping of packets as the buffer size gets smaller and the number of simultaneous readers gets larger. In the second patch, the per-client buffer is replaced by the buflock reader, and the spinlock name is changed to reflect the reduced area it covers. The third patch only has trivial changes, and the fourth patch is unchanged, but included for completeness.
