From 3cebde2413ba42504cf2c10ec1d47582912435cd Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Sun, 29 May 2011 21:20:59 -0700 Subject: [PATCH] vfs: shrink_dcache_parent before rmdir, dir rename The dentry_unhash push-down series missed that shink_dcache_parent needs to be called prior to rmdir or dir rename to clear DCACHE_REFERENCED and allow efficient dentry reclaim.
