This series of patches fix ubifs wrong budget space calculations,
which could make make_reservation() failed with ENOSPC error code
and let ubifs become read-only.

Zhihao Cheng (6):
  ubifs: Rectify space budget for ubifs_symlink() if symlink is
    encrypted
  ubifs: Rectify space budget for ubifs_xrename()
  ubifs: Add comments and debug info for ubifs_xrename()
  ubifs: Fix wrong dirty space budget for dirty inode
  ubifs: do_rename: Fix wrong space budget when target inode's nlink > 1
  ubifs: Reserve one leb for each journal head while doing budget
