Create a kmem cache of tracefs_inodes. To be more efficient, as there are lots of tracefs inodes, create its own cache. This also allows to see how many tracefs inodes have been created. Add helper functions: tracefs_alloc_inode() tracefs_free_inode() get_tracefs() Link: https://lkml.kernel.org/r/1690568452-46553-3-git-send-email-akaher@vmware.com Signed-off-by: Ajay Kaher <akaher@vmware.com> Co-developed-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Tested-by: Ching-lin Yu <chinglinyu@google.com> Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org>
