Subject: nfsv4: set hostname when creating nfsv4 ds connection
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a363e32e9459a0c5b199db9afa4b7dc143106012;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

nfsv4: set hostname when creating nfsv4 ds connection

We reference cl_hostname in many places for debugging purpose.
So make it useful by setting hostname when calling nfs_get_client.
