servers in traverses We should not remove locks of disconnected opens just like that. When getting the byte range lock record for a newly connected file handle, we still do the clean up, because in that situation, disconnected entries are not valid any more.

2012-06-28s3:brlock: s/int/uint64_t for fnumStefan Metzmacher1-1/+1
fsp->fnum and lock->fnum are uint64_t already and we should not truncate the value here. Currently this doesn't matter as we only use 16-bit. But as 'int' is int32_t and we later compare fnum with lock->fnum == fnum, the cast from int32_t to uint64_t goes via int64_t instead of uint32_t. This means even if fsp->fnum just uses 32-bit of the uint64_t we'll get the wrong result, as the implicit cast from a negative int32_t value to uint64_t adds 0xFFFFFFFF00000000. metze

This will be used to enforce a lock hierarchy between the databases. We have seen deadlocks between locking.tdb, brlock.tdb, serverid.tdb and notify*.tdb. These should be fixed by refusing a dbwrap_fetch_locked that does not follow a defined lock hierarchy.
