Hi,

When I checked the freeze feature for ext3 filesystem using fsfreeze
command at 3.1.0-rc4, I think the following deadlock problem happened.

How to reproduce:
 # mkfs -t ext3 /dev/sdd1
 # mount /dev/sdd1 /MNT
 # ./fsstress -d /MNT/tmp -n 10 -p 1000 > /dev/null 2>&1 &
 # fsfreeze -f /MNT
 # fsfreeze -u /MNT

Can you add this testcase to xfstests?

Christoph,

Isn't that just a matter of extending test 068 to ext4

That's a totally untested patch if someone wants to try it.
