Subject: ceph: increment i_version when doing a setattr with caps
X-Git-Tag: v6.1-rc1~37^2~3
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=b4b924c7a16e857b0715603456045251a49f2ea6;p=users%2Fdwmw2%2Flinux.git

ceph: increment i_version when doing a setattr with caps

When the client has enough caps to satisfy a setattr locally without
having to talk to the server, we currently do the setattr without
incrementing the change attribute.

Ensure that if the ctime changes locally, then the change attribute
does too.
