    revision 1.56\n\tlib/libpuffs/puffs.h: revision 1.124\nFix regression that has
    been introduced when the lookup/reclaim race\ncondition was addressed in libpuffs
    by counting lookups.\nThe fix assumes that cookies map to struct puffs_cookie,
    which has not\nbeen documented as a requirement for filesystems using libpuffs.
    As an\nexample, we got burnt by this assumption in libp2k (kern/46734), and\nwe
    fixed bit by actually mapping libp2k cookies to struct puffs_node.\nIt is unlikely,
    but there may be third party filesystems that use cookies\nunmapped to struct
    puffs_node, and they were left broken for now.\n- we introduce a puffs_init()
    flag PUFFS_FLAG_PNCOOKIE that let filesystems\ninform libpuffs that they map cookies
    to struct puffs_node. Is that flag\nis used, the lookup/reclaim race condition
    fix is enabled. We enable the\nflag for libp2k.\n- filesystems that use puffs_pn_new()
    obviouslty use struct puffs_node\nand gain PUFFS_FLAG_PNCOOKIE automatically even
    if they did not specify\nit in puffs_init(). This include all our PUFFS filesystem
    in-tree except\nlibp2k.\n- for filesystems not willing to use struct puffs_node,
    we introduce a\nreclaim2 vnop, which is reclaim with an additionnal lookup count
    argument.\nThis vnop let the filesystem implement the lookup/reclaim race fix
    on\nits own.\n"
