jbd2__journal_restart — restart a handle .
int jbd2__journal_restart ( | handle_t * handle, |
| int nblocks, | |
gfp_t gfp_mask); |
Restart a handle for a multi-transaction filesystem operation.
If the jbd2_journal_extend call above fails to grant new buffer credits
to a running handle, a call to jbd2_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. We preserve reserved handle if there's any attached to the
passed in handle.
