Subject: nilfs2: fix incorrect masking of permission flags for symlinks
Date: Thu, 23 Jun 2022 17:54:01 +0900
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.
