RELAY_LATE_SETUP_FIL(9)              relay interface support              RELAY_LATE_SETUP_FIL(9)



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.
