参数：

类型参数名称
struct linux_binprm *bprm
1340  secureexec或等于cap_elevated
1342  如果secureexec则
1344  pdeath_signal等于0
1353  如果rlim_cur大于Limit the stack by to some sane default: root can always* increase this limit if needed.. 8MB seems reasonable.则rlim_cur等于Limit the stack by to some sane default: root can always* increase this limit if needed.. 8MB seems reasonable.
1357  arch_pick_mmap_layout(mm, & rlim_stack)
1359  sas_ss_sp等于sas_ss_size等于0
1366  如果interp_flags按位与BINPRM_FLAGS_ENFORCE_NONDUMP或非uid_eq(current_euid(), current_uid())且gid_eq(current_egid(), current_gid())的值则set_dumpable stores three-value SUID_DUMP_* into mm->flags.
1370  否则set_dumpable stores three-value SUID_DUMP_* into mm->flags.
1373  Called immediately after a successful exec.
1374  perf_event_exec()
1375  These functions flushes out all traces of the currently running executable* so that a new one can be started
