Commit Message

From: Roberto Sassu <roberto.sassu@huawei.com>

With the recent introduction of LSM_ORDER_LAST, the 'integrity' LSM is
always initialized and the iint_cache is always created (the kernel panics
on error). Thus, the additional check of iint_cache in
integrity_inode_get() is no longer necessary.

This reverts commit 92063f3ca73aab794bd5408d3361fd5b5ea33079.
