[PATCH v2 25/26] NFSv4.1: Clear NFS_LAYOUT_BULK_RECALL when the layout segments are freed

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

 



Once all the affected layout segments have been freed up, clear the
NFS_LAYOUT_BULK_RECALL flag so that we can reuse the pnfs_layout_hdr
