Access Control Lists and UFS inodes

[Keith Michaels]

What can I look at in the inode structure for ufs that will
tell me if a file has Access Control Lists? I am processing
entire filesystems an cannot afford to call acl() on each path,
though I do have the inode structure as read directly from the
raw device. Is there a pointer in there to an ACL structure
that I can check?

Check the ic_shadow inode. My guess would be that since there
isn't room in the inode itself for the ACL, a shadow inode is allocated
to store the ACL, and is connected with the main inode via that field.
