This reverts commit 8cc5583abe6419e7faaebc9fbd109f34f4c850f2.
That commit causes several problems in Linux as described in the BZ.
In particular, after a while, other devices on the bus are no longer
usable even if those devices are not affected by the hotunplug.
This may be a problem in Linux, but we have not been able to identify
it so far. So better to revert this patch until we find a solution.
Also, Oracle, which initially proposed this patch for a problem with
Solaris, seems to have already reversed it downstream:

Thanks for the review.
By any chance do you have any information you can share regarding
[Orabug: 34905939] mentioned in the errata?
I'd like to better understand why this patch created problems in Linux,
but solved others in Solaris.
Apologies for the delay. I unfortunately can't provide any useful details. We
had a brief internal discussion about whether the Solaris or Linux driver was
technically correct per SCSI spec (I'm not sure we came to a conclusion). In any
case, we ultimately decided it didn't matter because we cannot tolerate a Linux
regression, and therefore Solaris should change to behave like Linux.
Thanks/regards,
