The patch titled Subject: mm/page_alloc.c: remove unused free_bootmem_with_active_regions has been added to the -mm tree. Its filename is mm-remove-unused-free_bootmem_with_active_regions.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-remove-unused-free_bootmem_with_active_regions.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-remove-unused-free_bootmem_with_active_regions.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Baoquan He <bhe@xxxxxxxxxx> Subject: mm/page_alloc.c: remove unused free_bootmem_with_active_regions Since commit 397dc00e249ec64e10 ("mips: sgi-ip27: switch from DISCONTIGMEM to SPARSEMEM"), the last caller of free_bootmem_with_active_regions() was gone. Now no user calls it any more. Let's remove it.
