Subject: congestion_wait(): don't use WRITE
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=58355c7876a0754377c37c8af948b4cd423410e2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

congestion_wait(): don't use WRITE

commit 8aa7e847d (Fix congestion_wait() sync/async vs read/write
confusion) replace WRITE with BLK_RW_ASYNC.  Unfortunately, concurrent mm
development made the unchanged place accidentally.

This patch fixes it too.
