From: Ingo Molnar Date: Fri, 11 Apr 2025 05:40:28 +0000 (+0200) Subject: x86/alternatives: Rename 'text_poke_queue()' to 'smp_text_poke_batch_add()' X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=732c7c33a0c17f68393497766445cbd2878ee95e;p=users%2Fdwmw2%2Flinux.git x86/alternatives: Rename 'text_poke_queue()' to 'smp_text_poke_batch_add()' This name is actively confusing as well, because the simple text_poke*() APIs use MM-switching based code patching, while text_poke_queue() is part of the INT3 based text_poke_int3_*() machinery that is an additional layer of functionality on top of regular text_poke*() functionality. Rename it to smp_text_poke_batch_add() to make it clear which layer it belongs to. Signed-off-by: Ingo Molnar Cc: Juergen Gross Cc: "H .
