# This testcase is trying to test recovery flow of generic filesystem, it needs
# creation time support on specified filesystem.
# With below steps, once the file is created, creation time attribute should be
# valid on the file, after we fsync that file, it expects creation time can be
# recovered after sudden power-cuts.
# 1. touch testfile;
# 1.1 sync (optional)
# 2. xfs_io -f testfile -c "fsync";
# 3. godown;
# 4. umount;
# 5. mount;
# 6. check creation time
