    Description

      Currently, to get uptodate LSOM data, we need to set llite.*.xattr_cache=0 to disable the xattr cache on client completely. This may lead that other kind of xattr can not be cached on client too.

      This ticket mainly focues on the heavy-weight solution to disable caching only for LSOM xattr data ("trusted.som") on client.
