Subject: [PATCH 0/4] IMA: making i_readcount a first class inode citizen

This is a repost of patches 1 - 4 of the ima-i_readcount patch set rebased
against security-testing/#next, as requested a while ago.  The patches are
also available from:
git://git.kernel.org/pub/scm/linux/kernel/git/zohar/ima-2.6.git/#next

This patchset separates the incrementing/decrementing of the i_readcount,
in the VFS layer, from other IMA functionality, by replacing the current
ima_counts_get() call with i_readcount_inc(). Its unclear whether this
call to increment i_readcount should be made earlier, like i_writecount.
Currently the call is situated immediately after the switch from put_filp()
to fput() for cleanup.

  IMA: convert i_readcount to atomic
  IMA: define readcount functions
  IMA: maintain i_readcount in the VFS layer
  IMA: remove IMA imbalance checking
