From b788dc51e4255b700f566a5d63a9c5028d631c77 Mon Sep 17 00:00:00 2001 From: James Simmons Date: Mon, 23 May 2016 20:35:08 -0400 Subject: [PATCH] staging: lustre: llite: drop acl from cache Commit b8a7a3a6 change get_acl() for posix xattr to always cache the ACL which increases the reference count. That reference count can be reduced by have ll_get_acl() call forget_cached_acl() which it wasn't. When an inode gets deleted by Lustre the POSIX ACL reference count is tested to ensure its 1 and if not produces an error. Since forget_cached_acl() was not called Lustre started to complain. This patch changes ll_get_acl() to call forget_cached_acl().
