From 6f033615ef8fb2374daa7e50a8ff68616bc850d2 Mon Sep 17 00:00:00 2001 From: Leon Hwang Date: Thu, 13 Aug 2026 00:48:43 +0800 Subject: bpf: Trim special_kfunc_list in verifier The commit 7619a0ee9340 ("bpf: Mark existing lock-safe kfuncs with KF_SPINLOCK_SAFE") dropped some helpers in verifier, which also eliminated the use of the following kfuncs from the special_kfunc_list: * bpf_arena_reserve_pages * bpf_stream_vprintk * bpf_stream_print_stack So, drop them from the special_kfunc_list.
