Its filename is mm-bootmem_info-export-register_page_bootmem_memmap.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-bootmem_info-export-register_page_bootmem_memmap.patch This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm 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 via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Frank van der Linden Subject: mm/bootmem_info: export register_page_bootmem_memmap Date: Wed, 29 Jan 2025 22:41:39 +0000 If other mm code wants to use this function for early memmap inialization (on the platforms that have it), it should be made available properly, not just unconditionally in mm.h Make this function available for such cases.
