Hi,
I=E2=80=99m getting the following crash during startup. It seems =
strongswan is setting a reqid.
Commit r363430 is on if_bridge. The IPSec interfaces are not bridged at =
all, so I=E2=80=99m clueless to why this crash relates to this commit. =
The only commonality is that the crash is Epoch related and the commit =
as well.

418 * Propagate our priority to any other waiters =
to prevent us
419 * from starving them. They will have their =
original priority
420 * restore on exit from epoch_wait().
