Subject: Client: Add Client::setlk and Client::getlk functions
X-Git-Tag: testing/wip-jcollin-testing-20250827.105003-tentacle~3^2~3
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=942c6168688ee552f202b8493e25e68df9f9d647;p=ceph-ci.git

Client: Add Client::setlk and Client::getlk functions

Also, removed CEPHFS_* errno's from setlk() and getlk() as Ceph has moved away from them.
