Its filename is mm-remove-hugetlb_inlineh.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-remove-hugetlb_inlineh.patch This patch will later appear in the mm-new branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Note, mm-new is a provisional staging ground for work-in-progress patches, and acceptance into mm-new is a notification for others take notice and to finish up reviews. Please do not hesitate to respond to review feedback and post updated versions to replace or incrementally fixup patches in mm-new. The mm-new branch of mm.git is not included in linux-next If a few days of testing in mm-new is successful, the patch will me moved into mm.git's mm-unstable branch, which is included in linux-next 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 various branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there most days ------------------------------------------------------ From: "Lorenzo Stoakes (ARM)" Subject: mm: remove hugetlb_inline.h Date: Mon, 14 Sep 2026 15:57:47 +0100 This header really makes little sense - every place it is included mm.h is also included, and the header itself includes mm.h, so it does nothing to reduce header size. It also oddly does an #ifdef around checking VMA_HUGETLB_BIT, however VMA_HUGETLB_BIT is unconditionally available, and will never be set if hugetlb is not enabled. Simply remove the header, eliminate the odd ifdeffery and place the predicates in mm.h. The naming of these predicates is odd, but to keep changes separate, we will address this in a separate patch. The file was never put into MAINTAINERS so there's no change required there. No functional change intended.
