Subject: [PATCH] lockdep: annotate on-stack completions, mmc
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0afffc723c8041a005134099847ac2a2fd0316a0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] lockdep: annotate on-stack completions, mmc

lockdep needs to have the waitqueue lock initialized for on-stack
waitqueues implicitly initialized by DECLARE_COMPLETION().

Annotate mmc_wait_for_req()'s on-stack completion accordingly.

Has no effect on non-lockdep kernels.
