[Qemu-devel] [PATCH] Removing O_LARGEFILE from block layer

[Qemu-devel] [PATCH] Removing O_LARGEFILE from block layer

[Richa Marwaha]

QEMU by default configures -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
so there is not need to mention O_LARGEFILE in the block layer.

Yay - I've previously suggested this, so it's nice to see it fixed.
