    ext4: Remove CONFIG_EXT4_FS_XATTR · 939da108

    Ted has sent out a RFC about removing this feature. Eric and Jan
    confirmed that both RedHat and SUSE enable this feature in all their
    product.  David also said that "As far as I know, it's enabled in all
    Android kernels that use ext4."  So it seems OK for us.
    
    And what's more, as inline data depends its implementation on xattr,
    and to be frank, I don't run any test again inline data enabled while
    xattr disabled.  So I think we should add inline data and remove this
    config option in the same release.
    
    [ The savings if you disable CONFIG_EXT4_FS_XATTR is only 27k, which
      isn't much in the grand scheme of things.  Since no one seems to be
      testing this configuration except for some automated compile farms, on
      balance we are better removing this config option, and so that it is
      effectively always enabled. -- tytso ]
