5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Song Liu <song@xxxxxxxxxx>
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.
Fixes: a10787e6d58c ("bpf: Enable task local storage for tracing programs")
