ocfs2: enable ocfs2_listxattr for special files
For special files in S_IFBLK/S_IFCHR/S_IFIFO type, we already have ocfs2_setattr and ocfs2_getattr enabled. It's confusing for user space if it can use setattr/getattr to control one attribute appointed but can not list attributes using listxattr for above type files: $ mknod /mnt/b b 0 0 $ setfattr -h -n trusted.name -v 0xbabe /mnt/b $ getfattr -n trusted.name /mnt/b getfattr: Removing leading '/' from absolute path names trusted.name=0sur4= $ getfattr -m trusted /mnt/b $ Fix it by enabling ocfs2_listxattr for ocfs2_special_file_iops. After the commit, fstests/generic/062 will pass.
