796 2002-10-28 Andreas Dilger <adilger@clusterfs.com>
799 - limit client IOV size to PTL_MD_MAX_IOV (611336, 191)
800 - defer open object destruction to close time (601981, 138)
801 - open/close OST file handle in obdo (OBD_MD_FLHANDLE) (601981, 138)

805 * protocol change to lustre_msg: move |version| and add |flags|

807 * lock replay: for LDLM_FL_REPLAY trust client to do right thing
808 * added replay of create, unlink, link and rename operations during
809 MDS failover; recovery should be much more robust now

856 - fixed lock conversion deadlock (611892)
857 - fixed the following of symlinks (614622)
858 * recovery: the server can remove locks from a client that dies, other
859 clients can make progress
860 * more extN patch fixes
861 * compile-time configurable ptlrpc buffer allocations
863 - collaborative read cache document
