Subject: ceph: invalidate pages even if truncate is pending
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=0840d8af3e6e40bcd5f2366698eb2755f88acfea;p=deliverable%2Flinux.git

ceph: invalidate pages even if truncate is pending

There is no reason not to invalidate pages when a truncate is pending.
Both throw out page cache pages.
