Its filename is mm-khugepaged-use-define_read_mostly_hashtable-macro.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-khugepaged-use-define_read_mostly_hashtable-macro.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: Nick Desaulniers Subject: mm/khugepaged: use DEFINE_READ_MOSTLY_HASHTABLE macro Date: Fri, 09 Jun 2023 16:44:45 -0700 These are equivalent, but DEFINE_READ_MOSTLY_HASHTABLE exists to define a hashtable in the .data..read_mostly section.
