From a26feccaba296bd0ae410eabce79cb3443c8a701 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Thu, 14 Apr 2016 00:30:16 +0200 Subject: [PATCH] ceph: Get rid of d_find_alias in ceph_set_acl Create a variant of ceph_setattr that takes an inode instead of a dentry. Change __ceph_setxattr (and also __ceph_removexattr) to take an inode instead of a dentry. Use those in ceph_set_acl so that we no longer need a dentry there.
