Looks good. Couple of comments:

** For all the lists under Section 5 (Solutions), wherever applicable,
QE like to have the information to test those (e.g.) fsdb commands

Key Limits
Create a large filesystem (say 5TB), create millions of inodes (regular
files, directories, symbolic links and special files), keep some of the
directories very big, enable user, group and tree quotas (say 10000
records each), create many security blobs (say 10000), create a lot of
hardlinks (say 10000), create snapshots at various points.  Test EEK on
such a volume and keep EEK run time as the base for future comparisons.
** How many million inodes?
** Any suggestions on number of inodes for files vs directories?
** Any suggestions on used data blocks (FS size)?

Thanks.
