Pratyush Yadav 0758b50692 tracing/ring-buffer: Only do full wait when cpu != RING_BUFFER_ALL_CPUS ... full_hit() directly uses cpu as an array index. Since RING_BUFFER_ALL_CPUS == -1, calling full_hit() with cpu == RING_BUFFER_ALL_CPUS will cause an invalid memory access. The upstream commit 42fb0a1e84ff ("tracing/ring-buffer: Have polling block on watermark") already does this. This was missed when backporting to v5.4.y. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.
