+TBD
+ * version v0_5_20
+ * bug fixes
+ - Fix ldlm_lock_match on the MDS to avoid matching remote locks (592)
+ - Fix fsfilt_extN_readpage() to read a full page of directory
+ entries, or fake the remainder if PAGE_SIZE != blocksize (500)
+ - Avoid extra mdc_getattr() in ll_intent_lock when possible (534, 604)
+ - Fix imbalanced LOV object allocation and out-of-bound access (469)
+ - Most intent operations were removed, in favour of a new RPC mode
+ that does a single RPC to the server and bypasses most of the VFS
+ - All LDLM resource ID arrays were removed in favour of ldlm_res_id
+ - Aggressively cancel local locks on DLM servers
+ - mds_reint_unlink sends EA to the client if it's the last nlink.
+ client uses that EA to unlink OST objects.
+ - mds_reint_{rename,unlink,link} were rewritten to take ordered locks
+ - recursive symlinks were fixed (439)
+ - fixed NULL deref in DEBUG_REQ
+ - filter_update_lastobjid no longer calls sync, which annoyed extN
+ - fixed multi-client small-writes to a single file problem (445)
+ - fixed mtime updates during file writes (607)
+ - fixed vector writes on obdfilter causing problems when ENOSPC (670)
+ - fixed bug in obd_brw_read/write() (under guise of testing 367)
+ - fixed Linux OST size reporting problem (444, 656)
+ - OST now updates object mtime with writes or setattr (607, 619)
+ - client verifies file size before zeroing page past EOF (445)
+ - OST now writes last allocated objid to disk with allocation (108)
+ - LOV on echo now works (409)
+ * protocol changes
+ - mds_reint_unlink sends a new buffer, with the EA included. this
+ buffer is only valid if body->valid & OBD_MD_FLEASIZE, which is only
+ set if a regular file was being unlinked, and it was the last link
+ - use PtlGet from the target for bulk writes (315)
+ - OST now updates object mtime with writes or setattr (607, 619)
+ - LDLM now has a grant-time callback to revalidate locked items, if
+ necessary (604)
+ - Many MDS operations were reorganized to combat race conditions
+ * other changes
+ - Merge b_intel branch (updated lprocfs code) - now at /proc/fs/lustre
+ - configure check to avoid gcc version 2.96 20000731-2.96-98) (606)
