Author: jeff Date: Tue Jun 8 07:49:02 2010 New Revision: 208906 URL: http://svn.freebsd.org/changeset/base/208906 Log: Import initial linux KPI compat code inspired by Luigi's kmod compat port. - Define linux bits using the same headers as linux uses for maximum include compatibility. The same include nesting is used where possible. - Some files are empty as nothing from them was required to build ofed. - Some implementations are still stubs (file, device, idr, dma-mapping). Sponsored by: Isilon Systems, iX Systems, and Panasas.
