nilfs2: fix incorrect masking of permission flags for symlinks
commit 5924e6ec upstream. The permission flags of newly created symlinks are wrongly dropped on nilfs2 with the current umask value even though symlinks should have 777 (rwxrwxrwx) permissions: $ umask 0022 $ touch file && ln -s file symlink; ls -l file symlink -rw-r--r--. 1 root root 0 Jun 23 16:29 file lrwxr-xr-x. 1 root root 4 Jun 23 16:29 symlink -> file This fixes the bug by inserting a missing check that excludes symlinks.
