revno: 2630.4.18
committer: Dmitry Lenev <dlenev@mysql.com>
branch nick: mysql-6.0-3726-w2
timestamp: Tue 2008-06-03 21:07:58 +0400
message:
WL#3726 "DDL locking for all metadata objects".
After review fixes in progress.
Now during upgrading/downgrading metadata locks we deal with
individual metadata lock requests rather than with all requests
for this object in the context. This makes API a bit more clear
and makes adjust_mdl_locks_upgradability() much nicer.
