JBD2__JOURNAL_RESTAR(9)

NAME
jbd2__journal_restart - restart a handle .

SYNOPSIS

int jbd2__journal_restart(handle_t * handle, int nblocks, gfp_t gfp_mask);

ARGUMENTS

    handle to restart

nblocks
    nr credits requested

gfp_mask

DESCRIPTION

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 capable of guaranteeing the requested number of credits. We preserve reserved handle if there's any attached to the passed in handle.
