Subject: [PATCH 0/8] remove d_time from dentry

dentry->d_time is not used by the VFS anymore, it's essentially a fs-private
data.  And it just wastes space in the dentry for the vast majority of
filesystems.

This series moves the few uses to ->d_fsdata.  Introduce ->d_allocate() method
to make it easier to allocate fs specific structure together with the dentry.

---
Miklos Szeredi (8):
  vfs: new d_allocate method
  ceph: don't use ->d_time
  cifs: don't use ->d_time
  vfat: don't use ->d_time
  fuse: don't use ->d_time
  nfs: don't use ->d_time
  ncpfs: don't use ->d_time
  vfs: remove ->d_time
