Subject: [Qemu-devel] [PATCH 0/2] osdep: warn if opening a file O_DIRECT on tmpfs fails
Date: Wed, 21 Aug 2013 14:26:39 +0200 [thread overview]
Message-ID: <1377088001-8783-1-git-send-email-stefanha@redhat.com> (raw)
Deepak C Shetty <deepakcs@linux.vnet.ibm.com> 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.

stubs: add error_report()
