Subject: [PATCH v3 7/9] bpf-lsm: Make bpf_lsm_kernel_read_file() as sleepable
Date: Wed, 2 Mar 2022 12:14:02 +0100	[thread overview]
Message-ID: <20220302111404.193900-8-roberto.sassu@huawei.com> (raw)
In-Reply-To: <20220302111404.193900-1-roberto.sassu@huawei.com>

Make bpf_lsm_kernel_read_file() as sleepable, so that bpf_ima_inode_hash()
or bpf_ima_file_hash() can be called inside the implementation of this
hook.
