Prasad Joshi 218b8eafbd Use truncate_setsize in zfs_setattr 
According to Linux kernel commit 2c27c65e, using truncate_setsize in
setattr simplifies the code. Therefore, the patch replaces the call
to vmtruncate() with truncate_setsize().

zfs_setattr uses zfs_freesp to free the disk space belonging to the
file.  As truncate_setsize may release the page cache and flushing
the dirty data to disk, it must be called before the zfs_freesp.

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
