( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1240514?usp=email ) Change subject: MDCACHE: skip parent content_lock on create when dirent caching is off ...................................................................... MDCACHE: skip parent content_lock on create when dirent caching is off On the create paths (open2, mkdir, mknod, symlink) the parent's content_lock only guards the dirent add, which is already gated on get_readdir_mode() == FSAL_RDDIR_CHUNK_ALWAYS. Take the lock only in that mode - mirroring mdcache_link() - so concurrent creates into the same directory no longer serialize when dirent caching is off.
