415 - Add capability to MDS protocol
416 - LDLM cancellations and callbacks on different portals
418 2002-10-28 Andreas Dilger <adilger@clusterfs.com>
421 - limit client IOV size to PTL_MD_MAX_IOV (611336, 191)
422 - defer open object destruction to close time (601981, 138)
423 - open/close OST file handle in obdo (OBD_MD_FLHANDLE) (601981, 138)
424 - move LDLM_ENQUEUE/CONVERT back to MDS portal (625069)
425 - abstract ll_lookup2, fix ll_revalidate2 to use abstraction (256)
426 - don't call obd_setattr in ll_file_release for destroyed objects
427 * protocol change to lustre_msg: move |version| and add |flags|
428 * protocol change to osc_punch: "start" in "o_size", "end" in "o_blocks"
429 * lock replay: for LDLM_FL_REPLAY trust client to do right thing
430 * added replay of create, unlink, link and rename operations during
431 MDS failover; recovery should be much more robust now
432 * remove failed OSCs from LOVs (only lov_create uses this so far)
433 * the lustre-HOWTO was brought (more) up to date (582544)

468 resulting in inconsistent data (605627)

474 - avoid going into recovery if user calls readlink() with a buffer
475 that's too small (613941)
476 - AST RPCs no longer require replies (614867) -- this may be changed
477 - don't crash server if client sends an IOV that's too big (611336)
478 - fixed lock conversion deadlock (611892)
479 - fixed the following of symlinks (614622)
480 * recovery: the server can remove locks from a client that dies, other
481 clients can make progress
482 * more extN patch fixes
483 * compile-time configurable ptlrpc buffer allocations
485 - collaborative read cache document
486 - Lustre Lite Performance CDR document-in-progress
