[patch 20/28] epoll: fix size check in epoll_create()

[Greg KH]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Davide Libenzi <davidel@xxxxxxxxxxxxxxx>

commit bfe3891a5f5d3b78146a45f40e435d14f5ae39dd upstream.

Fix a size check WRT the manual pages.  This was inadvertently broken by
commit 9fe5ad9c8cef9ad5873d8ee55d1cf00d9b607df0 ("flag parameters
add-on: remove epoll_create size param").
