# jbd2\_journal\_start\_reserved(9)

start reserved handle

## NAME

jbd2\_journal\_start\_reserved - start reserved handle

## SYNOPSIS

**int jbd2\_journal\_start\_reserved(handle\_t \*** *handle***, unsigned int** *type***, unsigned int** *line\_no***);**

## ARGUMENTS

*handle*

handle to start

*type*

for handle statistics

*line\_no*

for handle statistics

## DESCRIPTION

Start handle that has been previously reserved with **jbd2\_journal\_reserve**. This attaches *handle* to the running transaction (or creates one if there's not transaction running). Unlike **jbd2\_journal\_start** this function cannot block on journal commit, checkpointing, or similar stuff. It can block on memory allocation or frozen journal though.

Return 0 on success, non-zero on error - handle is freed in that case.
