a few questions about ext3 journal
A few wild ideas/questions :
1) Is there a way to check the size of the journal of an ext3 filesystem ?
I mean - the actually used size ; not the total size of the journal.
2) Would it be difficult to implement "freeze" of ext3 filesystem - that
is, blocking all I/O to the filesystem until it's "unfrozen" (XFS can do
that), for two purposes :

Oops
Hello everybody,
I've my Gentoo's /usr/portage on a loopback btrfs. Just wanted to sync and got
an oops. I've a rsync and a ls process in status D now. The system has been
in suspend (tuxonice 3.0-rc3) with mounted btrfs, perhaps that is related?
