Ioannis Ilkos b9d0592bba Remove kill_one_process tracepoint from lmkd 
We already emit a richer slice (including pid and oom score) so there's
no reason for the additional print event

Suren Baghdasaryan ab4c6d86e0 lmkd: set normal scheduling policy for reaper threads 
Reaper threads can take considerable time to free target's
memory running at RT priority that they inherit from LMKD.
This might prevent other critical tasks from being scheduled
while reaper threads are active.
Explicitly set reaper threads to run under normal scheduling
policy but set their nice value to ANDROID_PRIORITY_HIGHEST.

Ken Chen 4c18e91f22 Rename gpu_mem.o to gpuMem.o 
Underscore character may cause bpf prog/map naming collision. For
example, x.o with map y_z and x_y.o with map z both result in x_y_z
prog/map name, which should be prevented during compile-time.

aosp/2147825 will prohibit underscore character in bpf source name
(source name derives the obj name). Existing bpf modules with underscore
characters in source name need to be updated accordingly.

Bug: 236706995
Test: adb root; adb shell ls -l /sys/fs/bpf/ | grep gpuMem

Yongqin Liu bf819b5593 lmkd: fix the cgroup attribute name to MemCgroupEventControl 
which was CgroupEventControl before, but it's not the one
