I created 200 files and set acls on all of them. setxattr changed by 200. then I did an ls -l on the directory with the files in it and getxattr changed by 1. when I removed all the files reint changed by 200. I should quickly point out this was done on a 1.6.4 system as I'm waiting for access to remount the mds on my 1.6.5 systems with acls enabled. -mark
