Thanks for the link. Also can you try the third step on your standard linux kernel by omitting FAN_OPEN_PERM in the mask and share the observations of git clone operation. Does it succeed ?

Ran the fanotify example program(without any changes) on p9 mount point and performed git clone on another session. Git clone was successful. This program was using mask FAN_OPEN_PERM and FAN_CLOSE_WRITE. > 3.) Modified the fanotify example program to mark the mount point using mask FAN_CLOSE_WRITE only. Ran the git clone. The operation fails. I ran the rename_try reproducer only with FAN_CLOSE_WRITE events watched and could not reproduce. > > Is it something to do with mask ? > > I didn't get a chance to run on standard linux kernel.

I am using the 9p mount in the kvm test box that you can download from: https://github.com/tytso/xfstests-bld/blob/master/Documentation/kvm-quickstart.md Thanks, Amir.
