Hi,
This is the v20 of the patchset. This version has the following changes:
[PATCH v18 08/20] io: add qio_channel_readv_full_all_eof &
qio_channel_readv_full_all helpers
- Considers fds as part of the "data" for both
qio_channel_readv_full_all_eof() &
qio_channel_readv_full_all().
- Addresses some of the error scenarios
which were not addressed in the previous revisions
To touch upon the history of this project, we posted the Proof Of Concept
patches before the BoF session in 2018. Subsequently, we have posted 19
versions on the qemu-devel mailing list. You can find them by following
