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:
