Subject: [PATCH] Add Sparse annotations to SRCU wrapper functions in rcutorture
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=012d3ca8d85bf3ae5278ba897dd1ca3999247107;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] Add Sparse annotations to SRCU wrapper functions in rcutorture

The SRCU wrapper functions srcu_torture_read_lock and
srcu_torture_read_unlock in rcutorture intentionally change the SRCU
context; annotate them accordingly, to avoid a warning.
