Brian Behlendorf 21ade34764 Disable direct reclaim for z_wr_* threads 
The direct reclaim path in the z_wr_* threads must be disabled
to ensure forward progress is always maintained for txg processing.
This ensures that a txg will never get stuck waiting on itself
because it entered the following memory reclaim callpath.

  ->prune_icache()->dispose_list()->zpl_clear_inode()->zfs_inactive()
  ->dmu_tx_assign()->dmu_tx_wait()->tgx_wait_open()

It would be preferable to target this exact code path but the
kernel offers no way to do this without custom patches.  To avoid
this we are forced to disable all reclaim for these threads.  It
should not be necessary to do this for other other z_* threads
because they will not hold a txg open.

Closes #232

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
