    jffs2: update ctime when changing the file's permission by setfacl
    
    jffs2 didn't update the ctime of the file when its permission was changed.
    
    Steps to reproduce:
     # touch aaa
     # stat -c %Z aaa
     1275289822
     # setfacl -m  'u::x,g::x,o::x' aaa
     # stat -c %Z aaa
     1275289822                         <- unchanged
    
    But, according to the spec of the ctime, jffs2 must update it.
