[PATCH 00/20] tools/xenstore: do some cleanup and fixes

[Juergen Gross <jgross@xxxxxxxx>]

This is a first run of post-XSA patches which piled up during the
development phase of all the recent Xenstore related XSA patches.

At least the first 7 patches are completely independent from each
other. After those the dependencies are starting to be more complex.

This is a mixture of small fixes, enhancements and cleanups. Patch 2
was initially part of the XSA patches, which is the reason for having
a "Reviewed-by:" tag already. Even with fixing a previous commit it is
not urgent to put this patch in, so I don't think this is 4.17
material.

Juergen Gross (20):
  tools/xenstore: remove XEN_LIB_STORED and XENSTORED_ROOTDIR
  tools/xenstore: call remove_domid_from_perm() for special nodes
