    Subject[patch 015/108] IMA: open all files O_LARGEFILE
    2.6.30-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Eric Paris <eparis@redhat.com>

    commit 1a62e958fa4aaeeb752311b4f5e16b2a86737b23 upstream.

    If IMA tried to measure a file which was larger than 4G dentry_open would fail
    with -EOVERFLOW since IMA wasn't passing O_LARGEFILE. This patch passes
    O_LARGEFILE to all IMA opens to avoid this problem.
