# relay\_late\_setup\_files(9)

triggers file creation

## NAME

relay\_late\_setup\_files - triggers file creation

## SYNOPSIS

**int relay\_late\_setup\_files(struct rchan \*** *chan***, const char \*** *base\_filename***, struct dentry \*** *parent***);**

## ARGUMENTS

*chan*

channel to operate on

*base\_filename*

base name of files to create

*parent*

dentry of parent directory, **NULL** for root directory

## DESCRIPTION

Returns 0 if successful, non-zero otherwise.

Use to setup files for a previously buffer-only channel created by **relay\_open** with a NULL parent dentry.

For example, this is useful for perfomring early tracing in kernel, before VFS is up and then exposing the early results once the dentry is available.
