In fact what I wonder is how we missed that before. vfs_readdir() take the directory inode mutex | ------- copy_to_user() takes the mm->mmap_sem sys_unmap() takes mm->mmap_sem | ------- reiserfs_file_release() takes inode mutex The lock inversion can not happen as sys_getdents() can't be called after the directory is closed. I'm not sure what to do.
