Subject: NFSv4: Leases are renewed in sequence_done when we have sessions
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=be824167e33a8b747423c90f72479deb03255d54;p=deliverable%2Flinux.git

NFSv4: Leases are renewed in sequence_done when we have sessions

Ensure that the calls to renew_lease() in open_done() etc. only apply
to session-less versions of NFSv4.x (i.e. NFSv4.0).
