Subject: mm/page_alloc: rename FPI_TRYLOCK -> FPI_NOLOCK
Date: Wed, 15 Jul 2026 11:03:18 +0000

Patch series "mm/page_alloc: couple of followups for recent cleanups", v3.


This patch (of 4):

As discussed in the linked patch, the there is some inconsistency between
"trylock" and "nolock" nomenclature, let's align it.  Since "nolock" is
used in the public API it seems to have more mindshare so do that.

The linked patch did this for the ALLOC_ flag but forgot about FPI_.
