[PATCH 0/9] XArray: several cleanups

[Wei Yang]

Trivial cleanup for XArray.

No functional change.

Wei Yang (9):
  XArray: fix comment on Zero/Retry entry
  XArray: simplify the calculation of shift
  XArray: handle a NULL head by itself
  XArray: don't expect to have more nr_values than count
  XArray: entry in last level is not expected to be a node
  XArray: internal node is a xa_node when it is bigger than
    XA_ZERO_ENTRY
  XArray: the NULL xa_node condition is handled in xas_top
  XArray: take xas_error() handling for clearer logic
  XArray: adjust xa_offset till it gets the correct node
