2002-10-01 Phil Schwan <phil@clusterfs.com>
* version v0_5_13
* bug fixes:
- locks would be cancelled without throwing away data pages,
resulting in inconsistent data (605627)
- inode attributes were not always being refreshed (605627, 612449)
- lconf now continues to cleanup after lctl reports an error
- MDS now enforces user permissions (602707)
- lprocfs cleanup fixed, but not yet enabled (614157)
- fixed infinite server hang, should a client not respond to an AST
- avoid going into recovery if user calls readlink() with a buffer
that's too small (613941)
- AST RPCs no longer require replies (614867) -- this may be changed
- don't crash server if client sends an IOV that's too big (611336)
- fixed lock conversion deadlock (611892)
- fixed the following of symlinks (614622)
* recovery: the server can remove locks from a client that dies, other
clients can make progress
* more extN patch fixes
* compile-time configurable ptlrpc buffer allocations
* documentation
- collaborative read cache document
- Lustre Lite Performance CDR document-in-progress
