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.
