Hi Jaegeuk
these prints have been added since this change:

commit 3f8af6044713 ("scsi: ufs: Add some debug information to
ufshcd_print_host_state()")

https://patchwork.kernel.org/patch/11694371/

Cool, thank you for pointing this out. BTW, which branch can I see the -next
patches?


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.

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

Thanks,

Can Guo.
