bpf: lsm: Set bpf_lsm_blob_sizes.lbs_task to 0 stable inclusion from stable-v6.6.54 commit b3c10ac84c5a544ccd92ee4f891441df91a8cfbc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAZ3K2 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=b3c10ac84c5a544ccd92ee4f891441df91a8cfbc -------------------------------- commit 300a90b2cb5d442879e6398920c49aebbd5c8e40 upstream. bpf task local storage is now using task_struct->bpf_storage, so bpf_lsm_blob_sizes.lbs_task is no longer needed. Remove it to save some memory.
