Hello All, I am writing a stackable file system which would rename unlinked files to a particular folder say abc by default. So as any file /xyz is unlinked its renamed to /abc/xyz. I want to do this by overriding the unlink function of stackable file system. I am using wrapfs so I am modifying wrapfs_unlink for this. I have dentry of the unlinked file also I have inode of parent directory , now I need to have inode of /abc and dentry of /abc/xyz to call vfs_rename instead of vfs_unlink. I could find the dentry and vfsmount for the / so I have a dentry for / but I don't know how to get the dentry/inode of /abc I know I can get inode from dentry but I cannot get dentry also. I tried using lookup_one_len /abc is created but still it returns a negative inode , also I tried to use vfs_path_lookup to find the directory /abc it also returns an error. Am I using wrong functions? Or these methods see cache only not the actual directory structure ? Please help. -- Thanks and Regards , Gaurav -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
