	We should never change the type bits of ->i_mode or the method tables
(->i_op and ->i_fop) of a live inode.  Unfortunately, not all filesystems
took care to prevent that.

	rc2-based, one trivial conflict in fs/cifs/file.c on merge with mainline

  spufs: fix bogosity in S_ISGID handling (2021-03-12 23:13:52 -0500)

----------------------------------------------------------------
Al Viro (12):
      new helper: inode_wrong_type()
      vboxsf: don't allow to change the inode type
      orangefs_inode_is_stale(): i_mode type bits do *not* form a bitmap...
      ocfs2_inode_lock_update(): make sure we don't change the type bits of i_mode
      gfs2: be careful with inode refresh
      do_cifs_create(): don't set ->i_mode of something we had not created
      cifs: have ->mkdir() handle race with another client sanely
      cifs: have cifs_fattr_to_inode() refuse to change type on live inode
      hostfs_mknod(): don't bother with init_special_inode()
      openpromfs: don't do unlock_new_inode() until the new inode is set up
      9p: missing chunk of "fs/9p: Don't update file type when updating file attributes"
      spufs: fix bogosity in S_ISGID handling

David Howells (1):
      afs: Fix updating of i_mode due to 3rd party change

Jeff Layton (2):
      ceph: fix up error handling with snapdirs
      ceph: don't allow type or device number to change on non-I_NEW inodes
