Number of arguments for function vfs_permission is different for
original Linux kernel and for OpenVZ kernel. You should fix FUSE sources appropriately.

In sources of OpenVZ kernel we can see:
int vfs_permission(struct inode * inode, int mask, struct exec_perm * exec_perm)
Last argument, probably, should be NULL in your case.

what about using /dev/fuse in VE? [message #6963 is a reply to message #6330]

Hm, we had module build issue already solved by openvz developers and ALT Linux kernel maintainers (2.6.16-ovz-smp-alt4/x86_64); but fuse is not present in VE's /proc/filesystems being not FS_VIRTUALIZED.

Hence a suggestion: what if there was some hackery tool to bypass this check for a given VE and filesystem combination to facilitate with quick'n'dirty testing of more and less problematic FSes? For example with fuse, there are no kernel threads but userspace helper processes indeed. We'll have to hand-build kernel and reboot terminal server just to check whether a silly idea fails right from the start...

(the final goal on this particular route is getting ltspfs, which is the current LTSP's fuse-based rdesktop-borrowed way to work with remote devices, to work under OVZ)

PS: just in case, the module's loaded and working perfectly on HN and we've both created /dev/fuse (c 10 229), set perms and run vzctl set 102 --devnodes fuse:rw --save
