[merged] mm-fix-section-name-for-dataro_after_init.patch removed from -mm tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch titled
     Subject: mm: fix section name for .data..ro_after_init
has been removed from the -mm tree.  Its filename was
     mm-fix-section-name-for-dataro_after_init.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Kees Cook <keescook@xxxxxxxxxxxx>
Subject: mm: fix section name for .data..ro_after_init

A section name for .data..ro_after_init was added by both:

    commit d07a980c1b8d ("s390: add proper __ro_after_init support")

and

    commit d7c19b066dcf ("mm: kmemleak: scan .data.ro_after_init")

The latter adds incorrect wrapping around the existing s390 section, and
came later.  I'd prefer the s390 naming, so this moves the s390-specific
name up to the asm-generic/sections.h and renames the section as used by
kmemleak (and in the future, kernel/extable.c).
