This series fixes the detection of read/write violations on stacked filesystems. To be able to access the relevant dentries necessary to detect files opened for writing on a stacked filesystem a new d_real_type D_REAL_FILEDATA is introduced that allows callers to access all relevant files involved in a stacked filesystem while traversing the layers.

v2: - Simplified 2nd patch - Improvements on patch description on 1st patch
