Subject: perf: Don't schedule out/in pinned events on task tick
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7defb0f879bbcfe29e3c6f29d685d4f29b7a0700;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

perf: Don't schedule out/in pinned events on task tick

We don't need to schedule in/out pinned events on task tick,
now that pinned and flexible groups can be scheduled separately.
