Hi,
Since v5.10 ejecting removable USB devices on my desktop has resulted
in the kernel throwing errors and not cleanly unmounting the drives
(dirty bit is set upon remounting).
I have bisected this issue to commit 471bd0af544b ("sd: use
bdev_check_media_change"), and have confirmed the problem is still
present as of v5.11-rc7. It appears that several others have run into
this issue, as I see that there was a bugzilla report filed a month
ago [1]. There was also a bug report filed against udisks [2], and it
looks like they believe it is also a kernel issue.
Steps to reproduce the problem:
1. Insert removable USB storage device.
2. Use eject(1) to attempt to eject the USB device. (e.g. # eject /dev/sdd)
