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.
