Subject: [PATCH] md/raid5: Move stripe_request_ctx up
Git-commit: df6b0e205d1fe3fe1f2e9aaee9fc396b64e1c293
Patch-mainline: v6.0-rc1
References: jsc#PED-2766
Move stripe_request_ctx up. No functional changes intended.
This will be necessary in the next patch to release the batch_last
in the context before sleeping.
