# FS QA Test 507
#
# This testcase is trying to test recovery flow of generic filesystem, w/ below
# steps, once i_flags changes, after we fsync that file, we can expect that
# i_flags can be recovered after sudden power-cuts.
# 1. touch testfile;
# 1.1 sync (optional)
# 2. chattr +[AsSu] testfile
# 3. xfs_io -f testfile -c "fsync";
# 4. godown;
# 5. umount;
# 6. mount;
# 7. check i_flags
# 8. chattr -[AsSu] testfile
# 9. xfs_io -f testfile -c "fsync";
# 10. godown;
# 11. umount;
# 12. mount;
# 13. check i_flags
