[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: mm/madvise: remove len parameter of madvise_do_behavior()
has been removed from the -mm tree.  Its filename was
     mm-madvise-remove-len-parameter-of-madvise_do_behavior.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm/madvise: remove len parameter of madvise_do_behavior()
Date: Wed, 12 Mar 2025 09:47:50 -0700

Because madise_should_skip() logic is factored out, making
madvise_do_behavior() calculates 'len' on its own rather then receiving it
as a parameter makes code simpler.  Remove the parameter.
