[lustre-devel] [PATCH 2/9] lustre: remove EIOCBRETRY handling

[NeilBrown]

From: James Simmons <uja.ornl at yahoo.com>

With linux commit 41003a7bcfed ("aio: remove retry-based AIO")
AIO retry handling was removed due to it being buggy and no
one using it, including lustre. Since this is the case
remove EIOCBRETRY since it no longer in the kernel starting
with version 3.18.
