fist + fanout dentry problem

fist + fanout dentry problem

[Victor Mendez]

Hello,

Due to fist has not implemented the fan-out yet, I am working directly 
in the wrapfs generated code, to add this feature.
I am having a problem:
mount -t wrapfs -o dir=/mnt/devmnt,/mnt/devmnt2 /mnt/ptomnt /mnt /ptomnt
cp /etc/hosts /mnt/ptomnt/testfile
ls -l /mnt/ptomnt
and the command hang just before a call to vfs_readdir"/mnt/ptomnt", in 
strace: getdent64 after open de dir.

after reboot I can do the ls -l /mnt/ptomnt and work with the testfile 
copy there, aswell as on the branches: /mnt/devmnt and /mnt/devmnt2.

Any idea?

I also have a conceptual hesitage about the exactly work of vfs with the 
dentry->d_alias, that I am using for the dentry fan-out.

Any help will be pleasured.

Reagards.
