Hi, ulf
We find this bug on Intel-C3230RK platform for very small probability.
Whereas I can easily reproduce this case if I add a mdelay(1) or
longer delay as Jialing did.
This patch seems useful to me. Should we push it forward? :)
It seems like a very good idea!
Should we add a fixes tag to it?
That's cool, but how to add a fixes tag?
[Fixes] mmc: core: fix race condition in mmc_wait_data_done ? :)
A fixes tag points to an old commit which introduced the bug. If we can't find one, we can add a Cc tag to "stable". Just search the git log and you will find examples.
Like add one line as below?
Fixes: 2220eedfd7ae ("mmc: fix async request mechanism for sequential read scenarios")
That's it, Jialing. From my git blame, seems this bug has been
introduced for a long time, but I feel strange that no one had captured
it before you did.
Anyway, I will add a fixes tag and send v2 ASAP. :)
Kind regards
Uffe
