In addition to testing xfs_repair on inodes with malformed mode,
and fstat of those inodes on a mounted fs, try to also list content
of mock directory and readlink of mock symlink.
Readdir of mock directory triggers XFS assertion on kernel 4.9 with
XFS_DEBUG=y
XFS: Assertion failed:
rval == 0 || args->dp->i_d.di_size == args->geo->blksize,
file: /home/amir/build/src/linux/fs/xfs/libxfs/xfs_dir2.c, line: 634
A fix patch, as suggested by Darrick, changes this ASSERT() to
return -EFSCORRUPTED ("xfs: sanity check directory inode di_size").
Merging this test should be deferred to after fix patch is merged.
