[Xen-devel] [PATCH v3 0/4] xenstore: rework of transaction handling

[Juergen Gross <jgross@xxxxxxxx>]

Rework the transaction handling of xenstored to no longer raise
conflicts so often.

This series has been sent for pre-review to some reviewers before as the
series is related to XSA 206 which has been disclosed only today. So V1
and V2 have been non-public in order to speed up review process without
disclosing the XSA.

Changes in V3:
- don't always return EAGAIN in case of a failed transaction:
  it can be ENOMEM or ENOSPC, too.

Changes in V2:
- Rebase on top of those patches
- split patch 1 in two patches as suggested by Ian

Juergen Gross (4):
  xenstore: let write_node() and some callers return errno
  xenstore: undo function rename
  xenstore: rework of transaction handling
  xenstore: cleanup tdb.c
