From d36f34aadf184d8cc4c240de2b6319ccea8334bb Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Thu, 2 Feb 2006 10:43:45 -0800 Subject: IB: Enable FMR pool user to set page size This patch allows the consumer to set the page size of "pages" mapped by the pool FMRs, which is a feature already existing in the base verbs API. On the cosmetic side it changes ib_fmr_attr.page_size field to be named page_shift.
