From 48fec5d0a504dfbb302cb1dd24ebb0b82a46cce9 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Wed, 1 Jul 2015 16:27:46 +0800 Subject: ceph: EIO all operations after forced umount This patch makes try_get_cap_refs() and __do_request() check if the file system was forced umount, and return -EIO if it was. This patch also adds a helper function to drops dirty caps and wakes up blocking operation.
