( https://review.gerrithub.io/423878 Change subject: Fix bad assign logical caused use after freed ...................................................................... Fix bad assign logical caused use after freed A case of entry->attrs contains an old acl, but the new attrs request_mask without ATTR_ACL. Mdcache assign the acl from entry->attrs to attrs at mdc_update_attr_cache, but following fsal_copy_attrs assign it back, after that, both entry->attrs and attrs have the same acl, only one refrence. After that, the acl will be freed when release attrs, the entry->attrs->acl will be used after freed. This patch make sure the entry->attrs->acl is clean.
