Subject: NFSv4.1: handle NFS4ERR_NOSPC by CREATE_SESSION
X-Git-Tag: v5.16-rc3~18^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ea027cb2e1b59c76582af867b71d5c037fa6bb8e;p=thirdparty%2Fkernel%2Fstable.git

NFSv4.1: handle NFS4ERR_NOSPC by CREATE_SESSION

When the client receives ERR_NOSPC on reply to CREATE_SESSION
it leads to a client hanging in nfs_wait_client_init_complete().
Instead, complete and fail the client initiation with an EIO
error which allows for the mount command to fail instead of
hanging.
