Can you get some tracing for me?

echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_failure/enable
echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_rreq/enable
echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_sreq/enable
echo 1 >/sys/kernel/debug/tracing/events/netfs/netfs_folio/enable
echo 1 >/sys/kernel/debug/tracing/events/cachefiles/cachefiles_read/enable
echo 1 >/sys/kernel/debug/tracing/events/cachefiles/cachefiles_write/enable

(And compress the result before posting)

Thanks,
