Subject: md/raid5: break stripe-batches when the array has failed.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=626f2092c85ac847bb80b3257eb6a565dec32278;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

md/raid5: break stripe-batches when the array has failed.

Once the array has too much failure, we need to break
stripe-batches up so they can all be dealt with.
