    Subject[PATCH v16 00/22] Richacls (Core and Ext4)
    Date
    Here is another update to the richacl patch queue.  I still think these patches
    are ready for the next merge window.

    In reply to the previous posting (https://lkml.org/lkml/2015/11/11/60),
    Christoph has commented that richacls should use new syscalls as their
    user-space interface instead of xattrs; the arguments didn't seem very
    convincing though. So instead, I started looking into things that can be
    improved in the xattr code (see https://lkml.org/lkml/2015/12/2/343).


    Changes since the last posting:

    * Fix a typo (https://lkml.org/lkml/2015/11/10/681) that was causing
    getxattr to return 95 instead of failing with error EOPNOTSUPP when
    richacls were disabled.

    * The user namespace conversions for richacls have moved from the VFS
    into the get and set operations of richacl_xattr_handler; the VFS
    doesn't have to bother anymore.

    (POSIX ACLs arguably should behave the same way, but fixing that
    without breaking anything is tricky.)


    The complete patch queue is available in git form here:
