sys/security/mac mac_process.c
Log:
Eliminate a deadlock when creating snapshots. Blocking vn_start_write() must
be called without any vnode locks held. Remove calls to vn_start_write() and
vn_finished_write() in vnode_pager_putpages() and add these calls before the
vnode lock is obtained to most of the callers that don't already have them.
