Subject: proc/task_mmu: remove unnecessary inlines in function definitions
Date: Fri, 18 Sep 2026 08:33:13 -0700

It was pointed out in the previous reviews of this code that many
functions are specified as inline, which is unnecessary as the compiler
can make that decision by itself.  Cleanup these definitions.

No change in the resulting binary file size with gcc v15.2.0.  No
functional change intended.

[akpm@linux-foundation.org: fix CONFIG_NUMA=y && CONFIG_PROC_PAGE_MONITOR=n]
