Brian Behlendorf e2e7aa2df8 Add ZFS specific mmap() checks 
Under Linux the VFS handles virtually all of the mmap() access
checks.  Filesystem specific checks are left to be handled in
the .mmap() hook and normally there arn't any.

However, ZFS provides a few attributes which can influence the
mmap behavior and should be honored.  Note, currently the code
to modify these attributes has not been implemented under Linux.

* ZFS_IMMUTABLE | ZFS_READONLY | ZFS_APPENDONLY: when any of these
  attributes are set a file may not be mmaped with write access.

* ZFS_AV_QUARANTINED: when set a file file may not be mmaped with
  read or exec access.

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
