Subject: test_suite: make_fake_listdir -> make_fake_fstools
X-Git-Tag: 1.1.0~942^2~4
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=c69fdd6012c3b0ccef86f55cc597321f959e0d98;p=teuthology.git

test_suite: make_fake_listdir -> make_fake_fstools

fake_isfile was too simplistic.  Instead of using the path string
to determine whether it's a file, consider it a file if the
corresponding value in the dict is None.
