Subject: regression on BLKRRPART ioctl for EIO
Date: Tue, 6 Feb 2024 20:28:01 -0800	[thread overview]
Message-ID: <CAP9s-SrvNZROseNkpSL-p-qsO0RT6H+81xX4gg-TV71gQ_UbYA@mail.gmail.com> (raw)

Hi,

I am noticing a regression on the BLKRRPART ioctl after we changed the
blkdev_reread_part() logic to reopen the device with commit
68e6582e8f2dc32fd2458b9926564faa1fb4560e["reopen the device in
blkdev_reread_part"]

We now ignore the errors that used to be returned for
bdev_disk_changed(). I see that this was explicitly fixed for -EBUSY
(commit 68e6582e8f2dc32fd2458b9926564faa1fb4560e: block: return -EBUSY
when there are open partitions in blkdev_reread_part)

The regression I am particularly interested in is when we get an -EIO
error from the disk and BLKRRPART incorrectly reports success when it
actually failed to reread partitions.

Looking for advice.

Thanks,
Saranya
