[Andrew Morton]

The quilt patch titled
     Subject: mm: include swap.h in swapops.h
has been removed from the -mm tree.  Its filename was

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

Subject: mm: include swap.h in swapops.h
Date: Tue, 18 Aug 2026 12:50:26 +0100

swapops.h uses MAX_SWAPFILES_SHIFT, SWP_MIGRATION_READ and SWP_PTE_MARKER,
all of which swap.h defines, but does not include swap.h.  It compiles only
where the translation unit pulled swap.h in first.  leafops.h includes
swapops.h on the line above swap.h, so a file whose include list reaches
leafops.h before swap.h gets:

    In file included from include/linux/leafops.h:11:
    include/linux/swapops.h:88:21: error: use of undeclared
    identifier 'MAX_SWAPFILES_SHIFT'

A header that uses a definition has to include the header that provides it.
