Subject: e2fsprogs and fast symlink

Hi Ted,

The below test case fails x86
#ln -s sfdajsfsdsdfskjdgfkshdfkshdfkgdsjdsjdhsdfdafdsgakfasdgfsjksdsdsdfsd p 
#sync
#rm p
root@...3b165:~# /usr/local/e2fsprogs/sbin/e2fsck  -f  /dev/sda5
e2fsck 1.40.8 (13-Mar-2008)
Pass 1: Checking inodes, blocks, and sizes
Fast symlink 12 has EXTENT_FL set.  Clear<y>? 

ie because after deleting the file we have
debugfs:  stat <12>
Inode: 12   Type: symlink    Mode:  0777   Flags: 0x80000   Generation:

shouldn't e2fsprogs also look at whether the inode is in use ?
