Subject: NFS: Fix a missing initialisation when reading the SELinux label
X-Git-Tag: v5.15~19059^2~5
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=fcb63a9bd8427fc584229048ea14f1453dc9a2e1;p=mirror_ubuntu-kernels.git

NFS: Fix a missing initialisation when reading the SELinux label

Ensure that _nfs4_do_get_security_label() also initialises the
SEQUENCE call correctly, by having it call into nfs4_call_sync().
