v3:
- Fixed FUSE export aio_set_fd_handler() call that I missed and double-checked
for any other missing call sites using Coccinelle [Rich]
v2:
- Cleaned up unused return values in nvme and virtio-blk [Stefano]
- Documented try_poll_mode() ready_list argument [Stefano]
- Unified virtio-blk/scsi dataplane and non-dataplane virtqueue handlers
[Stefano]
The first patch improves AioContext's adaptive polling execution time
measurement. This can result in better performance because the algorithm makes
better decisions about when to poll versus when to fall back to file descriptor
monitoring.
The remaining patches unify the virtio-blk and virtio-scsi dataplane and
non-dataplane virtqueue handlers. This became possible because the dataplane
handler function now has the same function signature as the non-dataplane
handler function. Stefano Garzarella prompted me to make this refactoring.
