Brian Behlendorf 4db77a74a6 Suppress large kmem_alloc() warning 
The following warning was observed under normal operation.  It's
not fatal but it's something to be addressed long term.  Flag the
offending allocation with KM_NODEBUG to suppress the warning and
flag the call site.

README.markdown

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

Full documentation for building, configuring, and using ZFS can be found at: http://zfsonlinux.org
