[PATCH 3/3] NFSv4.1 do not clear NFS_DELEAGED_STATE until stateid is tested

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andy Adamson <andros@xxxxxxxxxx>

nfs41_open_expired() will test the delegation stateid based on
NFS_DELEGATED_STATE being set. If the stateid is bad, nfs4_open_recover
will clear the NFS_DELEGATED_STATE bit recovering the delegation.
