Its filename is bcachefs-update-min_heap_callbacks-to-use-default-builtin-swap.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/bcachefs-update-min_heap_callbacks-to-use-default-builtin-swap.patch This patch will later appear in the mm-nonmm-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: Kuan-Wei Chiu Subject: bcachefs: update min_heap_callbacks to use default builtin swap Date: Sun, 20 Oct 2024 12:01:59 +0800 Replace the swp function pointer in the min_heap_callbacks of bcachefs with NULL, allowing direct usage of the default builtin swap implementation. This modification simplifies the code and improves performance by removing unnecessary function indirection.
