* cluster_rbuild() have a race between incore and getblk. incore() returnsgluk2001-05-281-1/+2
| | | | | | | | | | | | zero indicating that buffer is not in a cache, but getblk() going to sleep: getblk->getnewbuf->tsleep. When getnewbuf() returns after a sleep, getblk() may find B_DONE buffer in hash and return it. When io operation finishes biodone() calls cluster_callback() which moves pages from one big cluster buffer into several component buffers and calls biodone() for every component buffer. Since there are a component buffer with B_DONE already set, biodone() panices: "biodone already". costa@ ok.
