Hi,
Just as the title says, for some case(OK, btrfs again) we need to catch
a file system in special timing.
In this specific case, we need to grab a btrfs image undergoing
balancing, just before the balance finished.
Although we can use flakey to drop all write, we still don't have method
to catch the timing of the that transaction.
On the other hand, we can tweak our local kernel, adding
msleep()/message and dump the disk during the sleep.
And the image I dumped can easily trigger btrfs kernel and user-space bug.
So I'm wondering if I can just upload a zipped raw image as part of the
test case?
Thanks,
Qu
