Subject: ceph: fix encoding of ino only (not relative) paths
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=795858dbd253462a67e14272edeaae73c6074b17;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ceph: fix encoding of ino only (not relative) paths

A 'path' consists of a starting ino and relative component.  Encode even
when there is no relative component.  This is primarily needed by the
NFS reexport code.
