From 9f3345d8ec5e226d116ddb7fb86ee71a08a3b9a7 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 8 Jul 2019 12:27:57 -0400 Subject: ceph: have __mark_caps_flushing return flush_tid Currently, this function returns ci->i_dirty_caps, but the callers have to check that that isn't 0 before calling this function. Have the callers grab that value directly out of the inode, and have __mark_caps_flushing return the flush_tid instead.
