From: Chao Yu <chao@xxxxxxxxxx> [ Upstream commit ca98d72141dd81f42893a9a43d7ededab3355fba ] As Pavel Machek reported in [1] This code looks quite confused: part of function returns 1 on corruption, part returns -errno. The problem is not stable-specific. [1] https://lkml.org/lkml/2021/9/19/207 Let's fix to make 'insane cp_payload case' to return 1 rater than EFSCORRUPTED, so that return value can be kept consistent for all error cases, it can avoid confusion of code logic.
