Subject[RFC PATCH v2 0/2] ima: Fix detection of read/write violations on stacked filesystems
Date
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.

Stefan

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

Stefan Berger (2):
ovl: Define D_REAL_FILEDATA for d_real to return dentry with data
ima: Fix detection of read/write violations on stacked filesystems
