Hello Masami,
I've udpated the objpool patch and did some function testings for X64 and
ARM64. Later I'll do the performance testings and more regressions.
Here are the changelogs:

I take it back, your patch effectively only does this.

The original code used conditional branching in the nfit_mem_cmp
function to compare two values and return -1, 1, or 0 based on the
result. However, the list_sort comparison function only needs results
<0, >0, or =0. This patch optimizes the code to make the comparison
branchless, improving efficie

Syzkaller uses the _RET_IP_ (also known as pc) to decode covered
file/function/line, and it employs pc ^ hash(prev_pc) (referred to as
signal) to indicate covered edge. If the pc for the same file/line
keeps changing across reboots, syzkaller will report incorrect coverage
data. Additionally, even
