Thank you for your suggestion.
I found the audit_permadded is set to 1 in audit_setup_perms() and setopt() after the AUDIT_PERM field.
But I think it is not enough.
When the watch is added and AUDIT_PERM is not added, the perm r,w,x,a should be added by kernel default.
So I think the audit_permadded should be set to 1 after a watch added.
I make a new patch for it. The "key" patch and new patch should use together.
Subject: [PATCH] When the watch is set, the audit_permadded should be set to 1
