Its filename was mm-gfp_types-fix-__gfp_account-gfp_kernel_account-documentation.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Johannes Weiner Subject: mm: gfp_types: fix __GFP_ACCOUNT, GFP_KERNEL_ACCOUNT documentation Date: Wed, 1 Jul 2026 14:21:02 -0400 Gregory points out that these descriptions are cursed and confusing, considering what these flags actually do. This is mostly due to historic implementation choices and cgroup1 baggage. Improve the description of their actual effects.
