Title:
  inline_data option on ext4 truncates symlinks

Status in “linux” package in Ubuntu:
  In Progress
Status in “linux” source package in Trusty:
  In Progress

Bug description:
  To replicate the bug, create two filesystems, one with `mkfs.ext4 -I
  256`, one with `mkfs.ext4 -I 256 -O inline_data`. An inode size of 256
  bytes is the default, but included here for clarity. To do this, you
  are going to need an `e2fsprogs` from trunk, or version 1.43 if it has
  been released.

  Mount the two filesystems, in each of them do:
      $ ln -s $(for i in {1..64}; do echo -n .; done) 64
      $ ln -s $(for i in {1..128}; do echo -n .; done) 128
      $ ln -s $(for i in {1..192}; do echo -n .; done) 192
      $ ls -l 64 128 192

  Both directory listings will show symlinks named `64`, `128` and
  `256`, each pointing to a filename with the corresponding amount of
  dots. This is the expected behavior.

  Unmount both filesystems, mount them again. Do the `ls -l` again.

  The default filesystem will show the same output as previously, the
  one with inline_data activated will show the `128` symlink pointing to
  a filename of only 64 dots.
