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.
