SYNOPSIS

9       int relay_late_setup_files(struct rchan * chan,
10                                  const char * base_filename,
11                                  struct dentry * parent);

ARGUMENTS

14       chan
15           channel to operate on
16
17       base_filename
18           base name of files to create
19
20       parent
21           dentry of parent directory, NULL for root directory
22

DESCRIPTION

24       Returns 0 if successful, non-zero otherwise.
25
26       Use to setup files for a previously buffer-only channel created by
27       relay_open with a NULL parent dentry.
28
29       For example, this is useful for perfomring early tracing in kernel,
30       before VFS is up and then exposing the early results once the dentry is
31       available.
