If anyone has any objections, please let me know. ------------------ From: Al Viro [ Upstream commit 764682e0118432260191d194edbdaff208260483 ] Again, the only thing it uses dentry for is dentry->d_fsdata; for the recursive call the situation is the same as with configfs_detach_prep() and the same observation about ->s_dentry->d_fsdata applies.
