[NFS-Ganesha-Devel] Re: 回复：Re: 回复：Re: Crash in mdcache_get_chunk

It seems repo "ssh://xxx@review.gerrithub.io:29418/ffilz/nfs-ganesha" doesn't have all the tags and branches. Thank you, dang. -------------------------------- ----- 原始邮件 ----- 发件人：Daniel Gryniewicz <dang(a)redhat.com&gt; 收件人：zhbingyin(a)sina.com, ganesha-devel <devel(a)lists.nfs-ganesha.org&gt; 主题：[NFS-Ganesha-Devel] Re: 回复：Re: Crash in mdcache_get_chunk 日期：2019年06月25日 23点26分 I don't think backporting a single commit will help, you'll need to find and backport all the readdir fixes (and anything they depend on). That said, the specific commit that removed it is here: b8fe6364c61c4ac0c086c67b4d06685beb55bc5f The tag is named V2.7.4. It's on the V2.7-stable branch here: https://github.com/nfs-ganesha/nfs-ganesha/tree/V2.7-stable Daniel On 6/24/19 6:42 PM, QR wrote: > Thank you, dang. > > I have two more questions. >     1.Is there a commit list which i can backport to 2.6.3 to fix this > issue? >     2.How to get 2.7.4 from git?
