X-Git-Tag: v2.6.35-rc1~522^2~91
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a64eae703b390185abe1d15fa932b48f04fa7fbb;p=karo-tx-linux.git

perf: Use generic sample reordering in perf sched

Use the new generic sample events reordering from perf sched,
this drops the need of multiplexing the buffers on record time,
improving the scalability of perf sched.
