svn commit: r285596 - head/sys/compat/cloudabi

[Ed Schouten]

Author: ed
Date: Wed Jul 15 09:14:06 2015
New Revision: 285596
URL: https://svnweb.freebsd.org/changeset/base/285596

Log:
  Make posix_fallocate() and posix_fadvise() work.
  
  We can map these system calls directly to the FreeBSD counterparts. The
  other filesystem related system calls will be sent out for review
  separately, as they are a bit more complex to get right.
