[Qemu-devel] [PATCH 0/2] osdep: warn if opening a file O_DIRECT on tmpfs fails

[Stefan Hajnoczi]

Deepak C Shetty <address@hidden> tried to open an image file
O_DIRECT on tmpfs and received EINVAL.  This error is too generic, making it
hard to figure out that the problem is -drive ...,cache=none on tmpfs.

Add a warning when opening a file O_DIRECT on tmpfs fails.

Stefan Hajnoczi (2):
  stubs: add error_report()
  osdep: warn if opening a file O_DIRECT on tmpfs fails
