Upstream commit 973c7a0d8a38 ("bpf: fix precision backtracking
instruction iteration") slightly changes the logic in the verifier which
results in the verifier log growing. This results in the log being too
small when loading the filterPowerSupplyEvents BPF program in Android,
and therefore causing the program loading to fail. Because this
program is labeled 'critical', a load failure forces a boot loop.
This BPF program exists on the vendor partition, and therefore we must
maintain the GRF/ treble boundary and modify the kernel logic.
The kernel's bpf log logic is refactored in the 6.4 kernel and
acknowledges the shortcomings of the existing approach which causes the
program load to fail. Instead of backporting the significant changes,
this change simply ignores the fact that the log is full.
For more information see commit 121664093803 ("bpf: Switch BPF verifier
log to be a rotating log by default")
