Subject[PATCH 0/4] input: evdev: Dynamic buffers (rev3)

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.



Henrik Rydberg (4):
input: Introduce buflock, a one-to-many circular buffer mechanism
input: evdev: Use multi-reader buffer to save space (rev3)
input: evdev: Convert to dynamic event buffer (rev3)
input: Use driver hint to compute the evdev buffer size
