[NFS-Ganesha-Devel] Change in ...nfs-ganesha[next]: mdcache: do not remove sentinel ref in cih module

Matthew DeVore has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/505607 ) Change subject: mdcache: do not remove sentinel ref in cih module ...................................................................... mdcache: do not remove sentinel ref in cih module Currently, the sentinel reference of an mdcache entry can be removed in _state_del_locked (see last line in that function) as well as in cih_remove_checked. After the last ref is removed, mdcache_lru_unref calls mdcache_lru_clean which calls mdc_clean_entry which calls cih_remove_checked, which attempts to 'put' the reference again, which finally leads to the -1 ref count. Other calls to cih_remove checked have been amended with a put ref, except one; mdc_up_try_release also tries to remove the sentinel ref twice: once through cih_remove_latched and again explicitly right before returning. This can also cause the refcnt to become negative, so its use of cih_remove_latched need not be amended with another put ref.
