Hi Herbert,
Changes v2: use sg_page(sg) only once
---8<---
For asynchronous operation, SGs are allocated without a page mapped to
them. If the SGL is freed, the code must only call put_page for an SG if
there was a page assigned to it in the first place.
This fixes a kernel crash when using io_
Hi Herbert,
This patch was tested with up to 64 iocb submitted with one io_submit call.
If you approve of this fix, I recommend that should go to the current 4.8
development cycle and to stable.

Hi,
After a deeply research about this crash, seems it is a specific
bug that only exists in armv8 board. And it occurs in this function
in arch/arm64/crypto/aes-glue.c.
static int ctr_encrypt(struct blkcipher_desc *desc, struct scatterlist *dst,
struct scatterlist *src, u
Managed API eliminates error handling code, thus reduces several lines
