Just some quick/random comments inline, because I don't have a ceph env
to actually test the patches..

Declare function local variables as 'local'.

I think it's better to dump the outputs from $SETFATTR_PROG to
$seqres.full, so we have debug logs when something went wrong. e.g.
$SETFATTR_PROG -n ceph.quota.max_files -v $val $dir >>$seqres.full 2>&1
Also, remove $seqres.full file before test.

We have a wrapper function around $GETFATTR_PROG called _getfattr(),
which is used to deal with different output formats from different
versions of getfattr tool, use the helper if possible.
And you need to filter $TEST_DIR here as well. And if you don't want the
"Removing leading '/' from absolute path names" messages, you could use
the "--absolute-names" option of getfattr, e.g.
_getfattr -n ceph.quota.max_files --absolute-names $dir | _filter_test_dir
