JBD2__JOURNAL_RESTAR(9) The Linux Journalling API 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
handle to restart

nblocks

nr credits requested

gfp_mask

memory allocation flags (for start_this_handle)

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.
