Thanks Jacob, but I still don't quite understand :-)
for example, I have a file a with mode set to 7755
# ls -l a
-rwsr-sr-t. 1 root root 2 Mar 15 23:46 a
# stat a
  File: 'a'
  Size: 2               Blocks: 2          IO Block: 4194304 regular file
Device: 34h/52d Inode: 48128       Links: 1
Access: (7755/-rwsr-sr-t)  Uid: (    0/    root)   Gid: (    0/    root)
Context: unconfined_u:object_r:unlabeled_t:s0
Access: 2022-03-15 23:42:19.390236000 +0800
Modify: 2022-03-15 23:48:19.760428000 +0800
Change: 2022-03-15 23:48:19.760350205 +0800

but in the event, the permission is "200107755", so it seems the first 7 is
setuid/setgid/sticky bit(all set), how about "20010"?
