Author: zont Date: Fri Sep 14 13:57:34 2012 New Revision: 240500 URL: http://svn.freebsd.org/changeset/base/240500 Log: MFC r239818: - Don't take an account of locked memory for current process in vslock(9). There are two consumers of vslock(9): sysctl code and drm driver. These consumers are using locked memory as transient memory, it doesn't belong to a process's memory. MFC r239895: - Remove accounting of locked memory from vsunlock(9) that I missed in r239818.
