# jbd2\_journal\_set\_triggers(9)

Add triggers for commit writeout

## NAME

jbd2\_journal\_set\_triggers - Add triggers for commit writeout

## SYNOPSIS

**void jbd2\_journal\_set\_triggers(struct buffer\_head \*** *bh***, struct jbd2\_buffer\_trigger\_type \*** *type***);**

## ARGUMENTS

*bh*

buffer to trigger on

*type*

struct jbd2\_buffer\_trigger\_type containing the trigger(s).

## DESCRIPTION

Set any triggers on this journal\_head. This is always safe, because triggers for a committing buffer will be saved off, and triggers for a running transaction will match the buffer in that transaction.

Call with NULL to clear the triggers.
