#     ovl: Always reevaluate the file signature for IMA
#     
#     Commit db1d1e8b9867 ("IMA: use vfs_getattr_nosec to get the i_version")
#     partially closed an IMA integrity issue when directly modifying a file
#     on the lower filesystem.  If the overlay file is first opened by a user
#     and later the lower backing file is modified by root, but the extended
#     attribute is NOT updated, the signature validation succeeds with the old
#     original signature.
#     
#     Update the super_block s_iflags to SB_I_IMA_UNVERIFIABLE_SIGNATURE to
#     force signature reevaluation on every file access until a fine grained
#     solution can be found.
