Subject: [PATCH v3 2/3] Revert "integrity: double check iint_cache was initialized"
Date: Thu,  9 Mar 2023 09:54:32 +0100	[thread overview]
Message-ID: <20230309085433.1810314-3-roberto.sassu@huaweicloud.com> (raw)
In-Reply-To: <20230309085433.1810314-1-roberto.sassu@huaweicloud.com>

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.
