This release adds Lustre FSAL, exporting several Lustre filesystems with the same server instance. A bug was found (during Bake-A-Thon) and fixed in OP4_READDIRPLUS (leading to a missing directory's entries). The directory content cache is now managed as a tree. Formerly used dir_chain were removed. Lock support has been added for FSAL_LUSTRE. For FSAL_LUSTRE, FSAL_XFS, FSAL_FUSELIKE, and FSAL_ZFS, a regression in readdir has been detected and fixed. The export list now supports IP ranges using the CIDR format.
