What do the functions pvfs_open, pvfs_lseek and pvfs_read do? It would be
good to see the code or pseudo-code for those as well (just in case
there is something wrong there).
I presume that they somehow make use of the pvfs2 system interface to
offer the above functionality.

Could you trigger this thru the VFS as well?
Or only thru the system interface?
Thanks for the reports
