[Qemu-devel] [PATCH 03/10] linux-user: Move target_to_host_errno_table[] setup out of ioctl loop |
Date: |
Tue, 14 Aug 2012 10:40:29 +0100 |
The code to initialise the target_to_host_errno_table[] array was
accidentally inside the loop through checking and initialising all
the supported ioctls. This was harmless but meant that we reinitialised the
array several hundred times on startup.
