Subject: client: fix "ceph.snap.btime" vxattr value
X-Git-Tag: v14.2.2~56^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=f3e68fff6e112ff6681ff2327c36d873aa3586b2;p=ceph.git

client: fix "ceph.snap.btime" vxattr value

The vxattr value incorrectly places a "09" prefix to the nanoseconds
field, instead of providing it as a zero-pad width specifier after '%'.
