            puffs_vfsops.c puffs_vnops.c

Log Message:
Fix a race in how new cookies are checked.  Previously the checking
was done separate of inserting the cookie into the lookup structure
and without any form of interlock.  This could lead to the same
cookie pointing to two different nodes.  Remedy the race by creating
a separate "checked and ready to be inserted" cookie list which
serves as an interlock without having to hold a fs-global creation
lock.
