New Revision: 356977
URL: https://svnweb.freebsd.org/changeset/base/356977
Log:
Relax locking requirements for in_pcballoc(). All pcbinfo fields
modified by this function are protected by the PCB list lock that is
acquired inside the function.
This could have been done even before epoch changes, after r286227.
