You have been subscribed to a public bug:

Whenever we use Fanotify to monitor "CIFS" mounted volumes and
try to write to a new file by doing:

echo "ABC" > /mnt/cifs/test.c

It takes around 10-15 secs to complete the write operation.

This happens only when we try to monitor "FAN_OPEN_PERM". Looks like
"FAN_OPEN_PERM" blocks and notifies only after 10-15 secs.
