is related to LU-16064 RPC from evicted client can corrupt data In Progress
Severity: 3
Rank (Obsolete): 9223372036854775807

 Description   

A client can get evicted during OST_READ's bulk, so the corresponding LDLM lock is cancelled and OST_DESTROY can get over the object. in this scenario ofd_commitrw_read() can meet non-existing (just removed) object. this is a valid case at least until LU-16064 is fixed.
