From e88a75ebe86c1df42f0ca9ab6e8fa50db26e7cef Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Thu, 24 Nov 2022 03:12:22 -0500 Subject: bcachefs: New bpos_cmp(), bkey_cmp() replacements This patch introduces - bpos_eq() - bpos_lt() - bpos_le() - bpos_gt() - bpos_ge() and equivalent replacements for bkey_cmp(). Looking at the generated assembly these could probably be improved further, but we already see a significant code size improvement with this patch.
