[Qemu-devel] [PATCH] libseccomp: add cacheflush to whitelist |

cacheflush is an arm-specific syscall that qemu built for arm
uses. Add it to the whitelist.

I'm not sure about the priority selection. Maybe cacheflush gets
used frequently enough that it deserves a higher one?
This patch isn't really necessary yet due to ae6e8ef11e6c: "Revert
seccomp tests that allow it to be used on non-x86 architectures",
which we can't revert until libseccomp has released a fix for
arm-specific syscall symbol naming, but when linking to a patched
libseccomp and reverting ae6e8ef11e6c, then this patch allows
guests to boot with '-sandbox on'.
