Subject: Re: [PATCH] mm: vmscan: Avoid signedness error for GCC 5.4

Hi all,

Apologies for the delayed response.

First, thank you all for your reminders which helped me understand 
exactly what caused the GCC 5.4 compile error, the proper fix, and the 
issue description.

However, this change might be unnecessary now.

Thanks to Nathan Chancellor's note in another email that the minimum 
version of GCC is being bumped to 8.1.[1]

My testing confirms that GCC 8.1 no longer exhibits this issue.

Thanks,
