From a43fb73101eaf6db0b33d22c152b338ab8b3edbb Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Fri, 17 Sep 2010 09:54:08 -0700 Subject: [PATCH] ceph: check mapping to determine if FILE_CACHE cap is used See if the i_data mapping has any pages to determine if the FILE_CACHE capability is currently in use, instead of assuming it is any time the rdcache_gen value is set (i.e., issued -> used). This allows the MDS RECALL_STATE process work for inodes that have cached pages.
