[PATCH v3 0/2] Two xattrs-related fixes for ceph

["Luís Henriques" <lhenriques@suse.de>]

Hi!

A bug fix in ceph has made some changes in the way xattr limits are
enforced on the client side.  This requires some fixes on tests
generic/020 and generic/486.

* Changes since v2:

  - patch 0001:
    Add logic to compute the *real* maximum.  Kudos to David Disseldorp
    for providing the right incantation to do the maths.  Also split
    _attr_get_max() in two, so that they can be invoked from different
    places in the test script.

  - patch 002:
    attr_replace_test now has an extra param as suggested by Dave Chinner,
    and added fs-specific logic to the script.  No need to have an exact
    maximum in this test, a big-enough value suffices.

* Changes since v1:

  - patch 0001:
    Set the max size for xattrs values to a 65000, so that it is close to
    the maximum, but still able to accommodate any pre-existing xattr

  - patch 0002:
    Same thing as patch 0001, but in a more precise way: actually take
    into account the exact sizes for name+value of a pre-existing xattr.

Luís Henriques (2):
  generic/020: adjust max_attrval_size for ceph
  generic/486: adjust the max xattr size
