Author: trasz Date: Fri Nov 6 09:39:35 2009 New Revision: 198975 URL: http://svn.freebsd.org/changeset/base/198975 Log: MFC r197789: Fix ACL support on sparc64. Turns out that fuword(9) fetches 64 bits instead of sizeof(int), and on sparc64 that resulted in fetching wrong value for acl_maxcnt, which in turn caused __acl_get_link(2) to fail with EINVAL.
