mutex_lock double lock in bcache #640

Closed GoogleCodeExporter closed 9 years ago

I fixed it in bcache.c in function:

static void free_more_memory(size_t size) 

line 72:
/*XXX */
if(bh->flags & BH_LOCKED) {
   continue;
}
but it's a quick & dirty hack

for more details you can contact me (Gaz)

Hi! I don't understood the problem, but you can try to add forgotten unlock:
line 79-81:
                        if (!free_all && bh->blocksize != size) {
                                bcache_buffer_unlock(bh);
                                continue;
                        }
