Subject: io: Add fsync call in tst-stat
X-Git-Tag: upstream/2.36~642
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ae132284092edc5885315b44cd17d5ea91177e49;p=platform%2Fupstream%2Fglibc.git

io: Add fsync call in tst-stat

io/tst-stat and io/tst-stat-lfs fail sporadically on the Fedora
builders, and this change hopefully helps to avoid the issue.
