Brian Behlendorf 3117dd0b90 Handle NULL in nfsd .fsync() hook 
How nfsd handles .fsync() has been changed a couple of times in the
recent kernels.  But basically there are three cases we need to
consider.

Linux 2.6.12 - 2.6.33
* The .fsync() hook takes 3 arguments
* The nfsd will call .fsync() with a NULL file struct pointer.

Linux 2.6.34
* The .fsync() hook takes 3 arguments
* The nfsd no longer calls .fsync() but instead used sync_inode()

Linux 2.6.35 - 2.6.x
* The .fsync() hook takes 2 arguments
* The nfsd no longer calls .fsync() but instead used sync_inode()

For once it looks like we've gotten lucky.  The first two cases can
actually be collased in to one if we stop using the file struct
pointer entirely.  Since the dentry is still passed in both cases
this is possible.  The last case can then be safely handled by
unconditionally using the dentry in the file struct pointer now
that we know the nfsd caller has been removed.

Closes #230

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!

$ ./configure
$ make pkg
