Add tracepoints for inode attribute updates, attribute revalidation, writeback start/end fsync start/end, attribute change start/end, permission check start/end. The intention is to enable performance tracing using 'perf'as well as improving debugging. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
