    Subject[PATCH v14 05/12] KEYS: Move KEY_LOOKUP_ to include/linux/key.h and set KEY_LOOKUP_FLAGS_ALL
    Date
    From: Roberto Sassu <roberto.sassu@huawei.com>

    In preparation for the patch that introduces the bpf_lookup_user_key() eBPF
    kfunc, move KEY_LOOKUP_ definitions to include/linux/key.h, to be able to
    validate the kfunc parameters.

    Also, define the new constant KEY_LOOKUP_FLAGS_ALL, to facilitate checking
    whether a variable contains only defined flags.
