[PATCH] kernel/module: disable cfi for do_mod_ctors

CFI failure when both CONFIG_CONSTRUCTORS and CFI_CLANG enabled. CFI failure at do_init_module+0x100/0x384 (target: tsan.module_ctor+0x0/0xa98 [module_name_xx]; expected type: 0xa540670c) Disable cfi for do_mod_ctors to avoid cfi check on mod->ctors[i](). Signed-off-by: Joey Jiao --- ker

[PATCH v2] module: Add CONFIG_MODULE_LOAD_IN_SEQUENCE option

When modprobe cmds are executed one by one, the final loaded modules are not in fixed sequence as expected. Add the option to make sure modules are in fixed sequence across reboot. Signed-off-by: Joey Jiao --- kernel/module/Kconfig | 11 +++ kernel/module/main.c | 3 ++- 2 files
