Volker Lendecke	db5bda56bf	tdb: add TDB_MUTEX_LOCKING support ... This adds optional support for locking based on shared robust mutexes. The caller can use the TDB_MUTEX_LOCKING flag together with TDB_CLEAR_IF_FIRST after verifying with tdb_runtime_check_for_robust_mutexes() that it's supported by the current system. The caller should be aware that using TDB_MUTEX_LOCKING implies some limitations, e.g. it's not possible to have multiple read chainlocks on a given hash chain from multiple processes. Note: that this doesn't make tdb thread safe!

Rusty Russell	90f463b25f	tdb: add tdb_rescue() ... This allows for an emergency best-effort dump. It's a little better than strings(1). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	2012-10-04 09:04:19 +09:30
