relay_late_setup_files — triggers file creation


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


struct rchan * chan

channel to operate on

const char * base_filename

base name of files to create

struct dentry * parent

dentry of parent directory, NULL for root directory


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.
