The patch titled Subject: memblock: remove unused memblock_mem_size() has been added to the -mm tree. Its filename is memblock-remove-unused-memblock_mem_size.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/memblock-remove-unused-memblock_mem_size.patch and later at https://ozlabs.org/~akpm/mmotm/broken-out/memblock-remove-unused-memblock_mem_size.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: Mike Rapoport <rppt@xxxxxxxxxxxxx> Subject: memblock: remove unused memblock_mem_size() The only user of memblock_mem_size() was x86 setup code, it is gone now and memblock_mem_size() funciton can be removed.
