ceph: use i_release_count to indicate dir's completeness
Current ceph code tracks directory's completeness in two places. ceph_readdir() checks i_release_count to decide if it can set the I_COMPLETE flag in i_ceph_flags. All other places check the I_COMPLETE flag. This indirection introduces locking complexity. This patch adds a new variable i_complete_count to ceph_inode_info. Set i_release_count's value to it when marking a directory complete. By comparing the two variables, we know if a directory is complete Signed-off-by: Yan, Zheng <zheng.z.yan@intel.com>
