mmputacl recursive option enhancement request

See this idea on ideas.ibm.com

Do you have any suggestions how we can do a recursive ACL change efficiently using mmputacl? For directory trees that include millions of files, running mmputacl on each file or directory using a file list generated by, let's say, the find command, can take huge amounts of time. Each acl change requires forking a process to mmputacl. Then, mmputacl requires an acl input file that it needs to read to set the acls. This is highly inefficient. mmputacl could benefit from a recursive option that can use PIT to quickly and efficiently traverse the directory hierarchy. I envision an mmputacl command with the following CLI:

mmputacl [-r --diracl aclfile --fileacl aclfile] | [[-d] [-i InFilename]] Filename 

The -r option would indicate recursive acl change. It would require an acl file for plain files and another for directories. If the -r option is not given, then the command behaves as it does today.

Thank you.

    This recursive option would be so helpful.. Especially with tools that create dirs ans subdirs while running for later sharing.

    We definitely need a more efficient recursive option.

    At this point, without a built-in recursive option, ACL updates can be painfully slow.  To wit, one of the "recent" updates on a large, directory-ladened filesets has been chugging along for some two weeks and is still not complete.
