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 Documentation/filesystems/Locking | 2 ++ Documentation/filesystems/vfs.txt | 3 +++ fs/ceph/dir.c | 6 +++--- fs/ceph/inode.c | 4 ++-- fs/ceph/mds_client.c | 4 ++-- fs/ceph/super.h | 2 +- fs/cifs/cifsfs.h | 10 ++++++++++ fs/cifs/dir.c | 6 +++--- fs/cifs/inode.c | 2 +- fs/dcache.c | 11 +++++++++++ fs/fat/namei_vfat.c | 19 +++++++++++++++---- fs/fuse/dir.c | 36 ++++++++++++++++-------------------- fs/ncpfs/dir.c | 21 ++++++++++++++++++--- fs/ncpfs/ncplib_kernel.h | 16 +++++++++++++--- fs/nfs/dir.c | 18 ++++++++++++++---- fs/nfs/getroot.c | 4 ++-- fs/nfs/namespace.c | 2 +- fs/nfs/unlink.c | 16 ++++++++-------- include/linux/dcache.h | 8 ++++---- include/linux/nfs_fs.h | 18 +++++++++++++++++- 20 files changed, 146 insertions(+), 62 deletions(-) -- 2.5.5
