From 70db4f3629b3476cf506be869ef9d15688d2d44a Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Tue, 21 Oct 2014 18:09:56 -0700 Subject: [PATCH] ceph: introduce a new inode flag indicating if cached dentries are ordered After creating/deleting/renaming file, offsets of sibling dentries may change. So we can not use cached dentries to satisfy readdir. But we can still use the cached dentries to conclude -ENOENT for lookup. This patch introduces a new inode flag indicating if child dentries are ordered. The flag is set at the same time marking a directory complete. After creating/deleting/renaming file, we clear the flag on directory inode. This prevents ceph_readdir() from using cached dentries to satisfy readdir syscall.
