Subject: dm: swap target postsuspend call and setting suspended flag
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4d4471cb5c1ec426c0f24818b270dc7b3ad7e655;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

dm: swap target postsuspend call and setting suspended flag

This patch moves DMF_SUSPENDED flag set before postsuspend.
No one should care about the ordering, because the flag set and
the postsuspend are protected by a single lock, md->suspend_lock,
and all strict flag-checkers take the lock.
