[Xen-devel] [PATCH v2 0/6] tools/libxl: Improvements to libxl__datacopier

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

To support migration v2, we need far more flexibility out of the datacopier.

This series adds the ability to read from an fd into a local buffer and to
copy a specific number of bytes rather than to EOF.  It also contains bugfixes
related to writing from a local buffer, and POLLHUP handling.

Changes in v2:
 * Rewrite most commit message (but no code change)
 * Rework the POLLHUP fix from scratch

Andrew Cooper (2):
  tools/libxl: Introduce min and max macros
  tools/libxl: Fix datacopier POLLHUP handling to not always be fatal

Ross Lagerwall (3):
  tools/libxl: Allow adding larger amounts of prefixdata to datacopier
  tools/libxl: Allow limiting amount copied by datacopier
  tools/libxl: Extend datacopier to support reading into a buffer

Wen Congyang (1):
  tools/libxl: Update datacopier to support sending data only
