[Qemu-devel] [RFC PATCH v1 0/3] gluster: conversion to coroutines and supporting write_zeroes |

Hi,
This series is about converting all the bdrv_aio* implementations in gluster
driver to coroutine based implementations. Read, write, flush and discard
routines are converted.
This also adds support for .bdrv_co_write_zeroes() in gluster and provides
a new preallocation option with qemu-img (-o preallocation=full) that can
be used for raw images on GlusterFS backend to create fully allocated and
zero-filled images.
Changes in v1
-------------
- Removed qemu_gluster_aio_cancel() and associated code.
- Calling qemu_aio_release() from where aiocb is created.
- s/qemu_gluster_aio_rw/qemu_gluster_co_rw.
- Use errno appropriately from read, write, flush, discard and zerofill routines
in gluster driver.
- Fix a memory leak in qemu_gluster_create().
- Proceed with glfs_zerofill() only if glfs_ftruncate() succeeds in
qemu_gluster_create().
Bharata B Rao (3):
gluster: Convert aio routines into coroutines
gluster: Implement .bdrv_co_write_zeroes for gluster
gluster: Add support for creating zero-filled image
