[dpdk-dev] [PATCH] vfio: fix stdbool usage without include

[Thomas Monjalon]

> This became visible by backporting the following for the 19.11 stable tree:
>  c13ca4e8 "vfio: fix DMA mapping granularity for IOVA as VA"
> 
> The usage of type bool in the vfio code would require "#include
> <stdbool.h>", but rte_vfio.h has no direct paths to stdbool.h.
> It happens that in eal_vfio_mp_sync.c it comes after "#include
> <rte_log.h>".
> 
> And rte_log.h since 20.05 includes stdbool since this change:
>  241e67bfe "log: add API to check if a logtype can log in a given level"
> and thereby masks the issue in >20.05.
> 
> It should be safe to include stdbool.h from rte_vfio.h itself
> to have bool present exactly when needed for the struct it defines
> using that type.

A line "Fixes" is missing for the record of the root cause.
