unsigned int *_new_isid
1791  sbsec等于s_security
1793  如果 which mount options were specified 按位与Non-mount related flags 且 labeling behavior 恒等于use mountpoint labeling 则
1795  _new_isid等于 SECURITY_FS_USE_MNTPOINT context for files
1796  否则如果 which mount options were specified 按位与SBLABEL_MNT且 fscreate SID 则
1798  _new_isid等于 fscreate SID
1799  否则
1800  dsec等于Get the security label of an inode.
1801  返回:security_transition_sid( & selinux_state, current SID , SID of this object , tclass, name, _new_isid)
