[Qemu-devel] [PATCH v2 04/20] 9p: linux: Fix a couple Linux assumptions |
Date: |

- Guard Linux only headers.
- Add qemu/statfs.h header to abstract over the which
headers are needed for struct statfs
- Define `ENOATTR` only if not only defined
(it's defined in system headers on Darwin).
Signed-off-by: Keno Fischer <address@hidden>
---
Changes since v1:
* New qemu/statfs.h header to factor out the header selection
to a common place. I did not write a configure check,
since the rest of 9p only supports linux/darwin anyway,
so there didn't seem to be much point, but I can write
one if requested.
* Now also covers fsdev/virtfs-proxy-helper.c
