[RFC PATCH 0/3] define new read_iter file operation rwf flag

[Mimi Zohar]

This patch set replaces the "integrity_read" file operation method,
as defined in the "ima: use fs method to read integrity data" patch,
with a new read_iter file operation "rwf" flag.  (The other patches
are the same.*)

The main difference between these approaches is whether IMA must be
explicitly enabled (opt-in), by defining the "integrity_read" file
operation method for each file system, or enabled by default, with
modifications as needed to the read_iter.

*The entire patch sets can be found in
git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity.git
next-integrity-read and next-read-iter.

  fs: define new read_iter rwf flag
  integrity: use call_read_iter to calculate the file hash
  fs: detect that the i_rwsem has already been taken exclusively
