The patch titled Subject: mm/memory-failure: move some function declarations into internal.h has been added to the -mm mm-unstable branch. Its filename is mm-memory-failure-move-some-function-declarations-into-internalh.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-memory-failure-move-some-function-declarations-into-internalh.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: Miaohe Lin <linmiaohe@xxxxxxxxxx> Subject: mm/memory-failure: move some function declarations into internal.h Date: Wed, 12 Jun 2024 15:18:32 +0800 There are some functions only used inside mm. Move them into internal.h. No functional change intended.
