Hi all, I have previously successfully used LoadPin [https://www.kernel.org/doc/html/latest/admin-guide/LSM/LoadPin.html] together with overlayfs, however commit a6518f "vfs: don't open real" introduces a regression. (from loadpin.c): /* file_dentry sees through overlays */ load_root = file_dentry(file)->d_sb; (here, load_root->s_bdev is NULL and not the actual block device from the lower layer) Questions: * Maybe this is expected behavior and I am doing something wrong? Maybe there is some build- or mount option that could fix the problem? * If this really is a bug in overlayfs then I would be happy to try to fix it - however as I am not familiar with the code I would very much appreciate if someone more knowledgeable could point me in the right direction. Thanks, Anders
