Richard Yao b41c9906dc Support ashift=13 for 8KB SSD block sizes
New SSDs are now available which use an internal 8k block size.
To make sure ZFS can get the maximum performance out of these
devices we're increasing the maximum ashift to 13 (8KB).

This value is still small enough that we can fit 16 uberblocks
in the vdev ring label.  However, I don't want to increase this
any futher or it will limit the ability the safely roll back a
pool to recover it.

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
