Hmm - with 2.3.99 more oopses in a week than around 0.99 in a year.
Many different people change the code, and nobody knows the rules.
I just got an oops mounting a floppy, and looking at what
went wrong it became clear that the author of the floppy driver
assumed the rule: check_media_change() can be called only after
open() has been called. Before the recent changes that was true:
We did blkfops->open(), and then read_super() which called
check_media_change().
Today check_disk_change() is called in get_sb_bdev() before
blkdev_get() does the open.
So various fixes are possible: move the check_disk_change()
call, or fix the floppy driver. Unfortunately the floppy
driver is a pile of kludges, so fixing it either means
adding one more kludge - this is the four-line solution -
or rewriting a lot of stuff.
