The mentioned change makes a difference only on ChromeOS.
Additionally, the CL only changes the log message levels.
Therefore, I don't think this CL increase a memory leakage on Linux.
If my opinion is incorrect, please reassign me.

Thanks

Predator and CL could not provide any possible suspects.

Using Code Search for the file, "PartitionAllocator.cpp" and observed there was some recent changes for the below file.

Suspect CL: https://chromium.googlesource.com/chromium/src/+/6e19c2610f76d08d8d45d104740c0512587a54aa
