Hi Jaegeuk,

This patch comes from a series of changes trying to fix and simplify
the UFS error handling. You can find the whole series here - they are
picked up on scsi-queue-5.10

https://lore.kernel.org/linux-scsi/1596975355-39813-10-git-send-email-cang@xxxxxxxxxxxxxx/

Besides, several more fixes for error handling based on above series are

https://lore.kernel.org/patchwork/patch/1290405/
&
https://lore.kernel.org/linux-scsi/159961731708.5787.8825955850640714260.b4-ty@xxxxxxxxxx/

I've mainline all above changes to Android12-5.4 and Android11-5.4.

I've seen the patches in Android branches. Thank you for the explanation.


Moreover, there are 2 more fixes on the way for error handling, I
will push them soon.

BTW, could you please take a look at these patches?

Thanks,


Sure, but since I am not in your cc or to list, so I don't know which
patches. Maybe you can add me when you push the next version? Thanks.

Regards,

Can Guo.


Thanks,

Can Guo.
