The quilt patch titled

of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Date: Wed, 5 Aug 2026 15:05:29 +0800

The last callers of mas_is_root_limits() were removed by commit
b8852ef30c67 ("maple_tree: remove maple big node and subtree structs"),
together with the maple subtree state (mast_*) code that used it.  As a
static inline it does not trigger -Wunused-function, so it went unnoticed.

Remove it. No functional change.
