The patch titled Subject: mm/page_alloc.c: use NODE_MASK_NONE in build_zonelists() has been added to the -mm tree. Its filename is mm-page_allocc-use-node_mask_none-in-build_zonelists.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-page_allocc-use-node_mask_none-in-build_zonelists.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-page_allocc-use-node_mask_none-in-build_zonelists.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: Wei Yang <richard.weiyang@xxxxxxxxx> Subject: mm/page_alloc.c: use NODE_MASK_NONE in build_zonelists() Slightly simplify the code by initializing user_mask with NODE_MASK_NONE, instead of later calling nodes_clear(). This saves a line of code.
