Subject: [PATCH] md: make sure recovery happens when add_new_disk is used for hot_add
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c361777fb9347a4d16b82272f7d3b234e94bef2d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] md: make sure recovery happens when add_new_disk is used for hot_add

Currently if add_new_disk is used to hot-add a drive to a degraded array,
recovery doesn't start ...  because we didn't tell it to.
