Restart a handle.
int journal_restart(handle_t * handle, int nblocks);
handle
handle to restart
nblocks
nr credits requested
Restart a handle for a multi-transaction filesystem operation.
If the journal_extend call above fails to grant new buffer credits to a running handle, a call to journal_restart will commit the handle's transaction so far and reattach the handle to a new transaction capabable of guaranteeing the requested number of credits.
