newbie question about a dbuf-arc eviction race
Hi,
Can a dbuf be in DB_CACHED state, db_holds == 0,
b_efunc != NULL while its db_buf is put on the
eviction list ? From an ASSERT in dbuf_do_evict(),
it appears that it can. If it can, I am wondering what
is preventing the following race
dbuf_hold_impl()
db = dbuf_find(dn, level, blkid);
...
if (db->db_buf && refcount_is_zero(&db->db_holds)) {
arc_buf_add_ref(db->db_buf, db);...
