Its filename is mm-damon-dbgfs-use-kmalloc-for-allocating-only-one-element.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-damon-dbgfs-use-kmalloc-for-allocating-only-one-element.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: Kenneth Lee Subject: mm/damon/dbgfs: use kmalloc for allocating only one element Date: Mon, 8 Aug 2022 15:00:19 -0700 Use kmalloc(...) rather than kmalloc_array(1, ...) because the number of elements we are specifying in this case is 1, kmalloc would accomplish the same thing and we can simplify.
