please note, that #25782 combo bug is partially (ocfs2 issue)
fixed on mainline but it forks in ugly way into two new bugs:

1).
use-after-free bug in soft-raid subsystem described later
in the thread: http://marc.info/?l=linux-kernel&m=129373800308277&w=2

2).
use-after-free bug in block layer:

Are these still a problem in 2.6.38/2.6.39-rc ?
