[PATCH 0/1] MR3598: ntdll: Add error and warning logs in more cases of memory exhaustion.

[Tim Clem (＠tclem)]

In my opinion we're far too quiet about mmap and allocation failures that will likely be fatal to the application. It generally takes some close inspection of +virtual or even +relay to detect running out of address space, e.g..

In my testing the added logs here shouldn't be too noisy - I've avoided them in the `try` functions and in cases where an error code is normal. I made the cross-process allocation failure a warning, because the target process itself will presumably log an error if it goes wrong.

I also explicitly logged errno in a few cases where we assume its value. That can help catch some exotic error cases.
