Subject: Re: Possible kernel fs block code regression in 6.2.3 umounting usb drives

With kerne. 6.2.3 if I simply plug in a usb external drive, mount it
and umount it, then the journal has a kernel Oops and I have submitted
a bug report, that includes the journal output, at
https://bugzilla.kernel.org/show_bug.cgi?id=217174

As soon as the usb drive is unmounted, the kernel Oops occurs, and the
machine hangs on shutdown and needs a hard reboot.

I have reproduced the same issue on three different machines, and in
each case downgrading back to kernel 6.2.2 resolves the issue and it
no longer occurs.

This would seem to be a regression in kernel 6.2.3
