Description

After eviction failed export stayed at stale list, a client had IO processing and reconnected during it. A client sent brw rpc with last lock cookie and new connection. The lock with failed export was found and assert was happened.
(ost_handler.c:1812:ost_prolong_lock_one())
ASSERTION( lock->l_export == opd->opd_exp ) failed:

I couldn`t reproduce it on top of master after 'LU-6271 osc: handle osc eviction correctly'. But master is affected when older client is working.
