[Qemu-devel] [PATCHv3 0/3] introduce max_transfer_length

[Peter Lieven]

This series adds the basics for introducing a maximum transfer length
to the block layer. Its main purpose is currently avoiding that
a multiwrite_merge exceeds the max_xfer_len of an attached iSCSI LUN.
This is a required bug fix.

Splitting up requests according to the max_transfer_length will follow
in a later series.

v2->v3: remove Patch 2 completely [Paolo]
v1->v2: do not throw errors but generate trace events in Patch 2 [Paolo]

Peter Lieven (3):
  BlockLimits: introduce max_transfer_length
  block/iscsi: set max_transfer_length
