Subject: [PATCH -next] NFSD: Fix error return code in nfsd4_interssc_connect()
Date: Thu, 3 Jun 2021 13:51:45 +0000 [thread overview]
Message-ID: <20210603135145.972633-1-weiyongjun1@huawei.com> (raw)
'status' has been overwritten to 0 after nfsd4_ssc_setup_dul(), this
cause 0 will be return in vfs_kern_mount() error case. Fix to return
nfserr_inval in this error case.
